Cathy Dennis

In 2019, Dennis returned to performing. She celebrated her 30th anniversary in the music business with a performance at London's Mighty Hoopla Festival.

Dennis dated Noel Fitzpatrick, and the relationship ended during the year that the Britney Spears song "Toxic", co-written by Dennis, was recorded. A 2019 article published in The Irish Times speculated that Fitzpatrick may be the subject of the song.

As of 2015, Dennis became a vocal affiliate with Galantis by first performing, uncredited, on their debut album Pharmacy on the tracks "Runaway (U & I)" and "Louder, Harder, Better". She later co-wrote their song "Love on Me" from their second album The Aviary and sang on five songs from their 2019 album Church.

According to news reports, Dennis was working on a new album under the name Sexcassettes, which she planned to release in 2008. She has collaborated with Mark Ronson on his album, The Business.

In 2005, Dennis won her first Grammy for co-writing Britney Spears's single "Toxic". Dennis's biggest success came in 2008 with Katy Perry's smash hit "I Kissed a Girl" co-written alongside Dr Luke, which ranks among the best-selling digital singles in history.

In 2004, Dennis was listed 66th in the Q Magazine list of the top 100 most influential people in music and in 2006, she won the UK music industry's Woman of the Year Award.

In 2001, Kylie Minogue had a worldwide hit with the Dennis and Rob Davis penned song "Can't Get You Out of My Head". The following year Dennis won the Best Dance Recording Grammy for writing "Come into My World". She followed that up with Britney Spears's hit song "Toxic" which also won the Grammy for Best Dance Recording. Dennis had a string of hits with S Club 7; she wrote almost all their hit singles such as "Never Had a Dream Come True", and also worked on the singles for the spin-off group S Club Juniors which was a younger version of S Club 7. Dennis wrote hit songs for Céline Dion, Delta Goodrem, and for Hear’Say and Bardot. She also wrote the fastest selling debut single in UK history for recording artist Will Young, the winner of the British music competition reality show Pop Idol, and his runner-up Gareth Gates. Dennis wrote the theme song to the television series American Idol. She wrote several songs for former S Club 7 member Rachel Stevens including "Sweet Dreams My LA Ex", and also two songs for Phil Roy, one of which was on the soundtrack for the film As Good as It Gets starring Jack Nicholson and Helen Hunt.

Dennis has written a number of award-winning songs and international hit singles. Her first success was with "Bumper to Bumper", the B-side to the Spice Girls' hit "Wannabe". Dennis continued this success by co-writing the Pop Idol theme (re-used for numerous international remakes of the show, including American Idol), and writing for Idol contestants, including Kelly Clarkson, Will Young, Gareth Gates, and Clay Aiken. Clarkson's single "Before Your Love" (a double a-side with "A Moment Like This") was Dennis's first US No. 1. Dennis' "Can't Get You Out of My Head" (recorded by Kylie Minogue) spent four weeks at number one in Britain, while also rekindling interest in Minogue in America, where it hit no. 7 on the Billboard Hot 100. With over three million copies sold worldwide, "Can't Get You Out of My Head" became the second highest selling single in 2001.

In 1996, Dennis changed her musical style: away from the dance-pop sound of previous releases, to a more traditional singer-songwriter approach. The resulting album, Am I the Kinda Girl?, was more in keeping with the Britpop sound of bands such as Blur and performers such as Stephen Duffy, and featured collaborations with Guy Chambers of The Lemon Trees and Andy Partridge of XTC. The LP spawned three hits on the UK singles chart: "West End Pad", the album's opening track (No. 25), followed by her final Top 40 hit in the UK, a cover of the Kinks' classic "Waterloo Sunset", which made No. 11 during 1997, and that same year, her last solo single, "When Your Dreams Turn to Dust", which peaked at No. 43.

Dennis released her second album, Into the Skyline, in September 1992, written with a focus toward the US market. The album featured the singles "You Lied to Me", "Irresistible", "Moments of Love," "Falling", and "Why" – the latter was credited to D Mob with Dennis. The album got to No. 8 in the UK Albums Chart, whilst in the US Billboard Hot 100, "You Lied to Me" was a Top 40 hit - her final American Top 40 single as a performer - and "Irresistible" made the Adult Contemporary Top 10; however, the album descended the chart rapidly. Dennis experienced a brief peak of fame, making a cameo in Beverly Hills, 90210 singing the songs "Moments of Love" (a minor US Adult Contemporary chart hit), "Why" (in the episode, not to feature D Mob) and "Touch Me (All Night Long)". In Japan, the album was called Into the Skyline +1, and featured three extra tracks: "Nothing Moves Me", a previous B-side, and two tracks that were both released as singles, "It's My Style", and "Love's a Cradle". She also provided background vocals on PM Dawn's US Top 10 and UK Top 20 hit "Looking through Patient Eyes", released in 1993.

Dennis achieved her first success as a vocalist with D Mob, when their single "C'mon and Get My Love" reached No. 15 in the UK Singles Chart and No. 10 in the Billboard Hot 100 in 1989. It is regarded as an underground classic in the dance music field, and a second collaboration with D Mob, "That's the Way of the World", was also a hit. It was followed by Dennis's debut album, Move to This. She subsequently scored three solo hits, all of which reached the UK Top 20 and the US Top 10. She enjoyed considerable success in Japan in the early 1990s. The three solo hits were: "Just Another Dream" (UK No. 13, US No. 9, Australia No. 14), which featured D Mob on backing vocals; a cover of the Wish and Fonda Rae 1984 club hit "Touch Me (All Night Long)" (UK No. 5, US No. 2, Australia No. 16), which is probably her most remembered hit to date; and "Too Many Walls" (UK No. 17, US No. 8, Australia No. 57).

Educated at Taverham High School, as a teenager she was spotted recording Stevie Wonder-influenced demos at The Kitchen in Norwich with her father (himself an experienced musician and local restaurateur) on piano. At the time she was working for Norwich Union. In 1986, Simon Fuller signed Dennis when she was only 17 to his 19 Management company and to label Polydor, and this began a career-long association with the impresario that has seen Dennis provide songs for many Fuller-related artists and projects.

"Touch Me (All Night Long)" stayed at No. 2 on the Billboard Hot 100 for two weeks, and was kept out of the No. 1 spot by Hi-Five's "I Like The Way (The Kissing Game)" in the first week, and Mariah Carey's "I Don't Wanna Cry" in the second week. The song was a cover and lyrical reworking of a 1984 single by Wish featuring Fonda Rae, which had peaked at No. 70 on the US R&B chart that year. "Touch Me (All Night Long)" reached No. 1 on the US Hot Dance Club Play chart, and its follow-up, "Too Many Walls", which Dennis co-wrote with Anne Dudley of Art of Noise (who also co-wrote the ABC track "All of My Heart"), was a No. 1 Adult Contemporary hit in the United States. It was around this time Dennis agreed to join Club MTV's first tour, booked for six weeks. She dropped out on the third date, later publicly accusing one of Milli Vanilli's members (the tour's headline act) of sexual harassment. During this period, she recorded a song called "Find the Key to Your Life" with David Morales, for the soundtrack to the movie Teenage Mutant Ninja Turtles II: The Secret of the Ooze. Subsequent releases were only minor hits.
