Warren Entner

In 1970, he married the Welsh actress, model and beauty queen, Miss World 1961, Rosemarie Frankland. In 1976, she gave birth to their only child together, a daughter, Jessica. The couple divorced in 1981. He was married again on May 25, 1985, to Stacey Elizabeth Babbitt, who gave birth to his second child, Lauren, in 1986.

Entner had the opportunity to network with many famous groups and musicians playing these large festivals. This helped him fine tune his skills as a group manager. It was with The Grass Roots that Entner practiced his first efforts as band manager that he would fine tune to become a professional manager for other groups after 1974. Entner identified several songs written by other composers that proved successful when The Grass Roots covered them. He was instrumental in identifying "Let's Live For Today", "Midnight Confessions" and "Lovin' Things" (written by Artie Schroeck) to name a few.

Entner and his group The Grass Roots played at Newport Pop Festival 1969 at Devonshire Downs which was a racetrack at the time but now is part of the North Campus for California State University at Northridge. They played on Sunday June 22 which was the final day of the festival as their top twenty hit "Wait A Million Years" was hitting the airwaves. In Canada, they played at the Vancouver Pop Festival at the Paradise Valley Resort in British Columbia in August 1969 (see List of electronic music festivals).

Entner and his group The Grass Roots played at the Fantasy Fair and Magic Mountain Music Festival on Sunday June 11, 1967, in the "summer of love" as their top ten hit "Let's Live For Today" was hitting the airwaves. This music festival is important because it occurred before the Monterey Pop Festival but did not have a movie to document it for the ages (see List of electronic music festivals). On Sunday October 27, 1968, they played at the San Francisco Pop Festival and then played at the Los Angeles Pop Festival and Miami Pop Festival in December of that year as their top ten hit "Midnight Confessions" was hitting the airwaves.

Warren Entner (born 1944) is an American singer, songwriter, organist and guitarist for the rock and roll band, The Grass Roots. He then became a manager for several successful heavy metal/rock groups.
