Murray Cook

In early 2018, Cook gave an "energetic performance" in the music video for the DZ Deathrays song, "Like People", which went viral online. He appeared with the group at the rock festival Splendour in the Grass in July 2018.

Cook's nickname is "Muzz". He is married and has two children, a son and a daughter. In 2018, he told the New Castle Herald, "I’m a big fan of music in general and go to see lots of bands".

While exploring other projects, Cook met Lizzie Mack, a member of the Sydney soul-rock band The Soul Movers, who along with Radio Birdman guitarist Deniz Tek and founder of The Soul Movers, were relaunching the group. In 2015, Cook began writing songs with Mack and decided to focus on the band and use it as his "main creative outlet" In 2017, the group recorded Testify, "an album of energetic blues, soul and rock". The album was recorded at The Wiggles' studio in northwest Sydney and Jeff Fatt performed keyboards for the group. In 2019, the group recorded Bona Fide, which the Sydney Morning Herald called "a stunning album". The album, which as Cook stated, included "more roots-oriented songs to try to reflect a wide range of American music styles", and was recorded in the U.S.' "premier soul studios" such as Sun Studios in Memphis, Tennessee, and FAME Studios in Muscle Shoals, Alabama.

Cook told the Newcastle Herald, about his music career after his retirement from The Wiggles, "I was kind of feeling my way for a few years, I guess". In addition to continuing to play with Bang Shang A Lang, he "began to explore other adult musical projects". He played keyboard on his "long time friend and associate", jazz musician Marlene Cummins' 2014 album Koori Woman Blues and wrote a track for the album, "The Blues It Knows Your Name", which was inspired by and written for Cummins. He performed lead guitar for the Proposition, "a Sydney-based guitar pop band fronted by singer-songwriter Luke Russell" on their 2015 album, Edge of the Dancefloor. Also in 2015, Cook was involved in the production of the play Sons of Sun, which was about American music producer Sam Phillips. In October 2017, Cook played guitar for the tribute show "The Nancy Sinatra/Lee Hazlewood Experience" with Zoe Carides and Scott Holmes in Newcastle, New South Wales.

On 17 May 2012, it was announced that Cook, along with Greg Page and Jeff Fatt, would be retiring from The Wiggles at the end of the year. He was replaced by Wiggles cast member Simon Pryce. Cook and the others expected to remain involved with the creative and production aspects of the group. In 2013, Cook served as the group's tour manager.

Cook, along with the other three original members of The Wiggles, was made a Member of the Order of Australia in 2010 "for service to the arts, particularly children's entertainment, and to the community as benefactors and supporters of a range of charities". In 2015, he was one of the members of the Australian jury for the Junior Eurovision Song Contest.

Cook was conscious that he was probably the first guitarist children would see, and said, "I always think that if it inspires kids to play guitar later on that would be great. I think it would be really nice if in 15 years I read that somebody got into guitar playing because of [The] Wiggles". Guitar Magazine speculated that since Cook was one of the first guitarists children were exposed to, he might be the most influential guitarist in the world. Cook's major musical influences were The Beatles, The Rolling Stones, The Who, and Eric Clapton. In 2007, Cook owned a collection of thirty vintage guitars.

As a member of the Wiggles, Cook wore a red skivvy and served as an instrumentalist and vocalist. He came up with The Wiggles' signature index finger-wagging move after watching professional ten pin bowlers do the move on television. He was considered the intellectual and analytical member of the group (something referred to in several episodes of their TV show), so he acted as mediator for their group decisions. When The Wiggles received honorary degrees from the Australian Catholic University in 2006, Cook gave the commencement speech to the graduates.

After "a career as a struggling musician in Sydney", Cook returned to university and studied early childhood education at Macquarie University, where he met Anthony Field and Greg Page and formed The Wiggles in 1991. Cook worked as a preschool teacher for two years before the success of The Wiggles forced him to quit. According to Field, Cook would have been content to "continue teaching and perhaps move into an academic role in the field. He knows his stuff and is simply great with children".

Cook played the guitar in the late 1980s bands The Transistors and Finger Guns before joining the Sydney-based band Bang Shang a Lang. (He continued to play for Bang Shang a Lang in Sydney, when not on tour with The Wiggles.)
