John Clifford Farrar, born on November 8, 1946, in Melbourne, Australia, is a renowned music producer, songwriter, arranger, singer, and guitarist. He began playing guitar at the age of 12 and started his music career in 1961 with The Jaguars, a band he formed with his brother. Farrar gained prominence as a member of several rock and roll groups, including The Mustangs, The Strangers, Marvin, Welch & Farrar, and The Shadows.

In 1964, Farrar joined The Strangers, which became the house band for the popular TV music program "The Go!! Show." This opportunity led to collaborations with artists like Roy Orbison and the Beach Boys. In the late 1960s, Farrar moved to the UK and joined The Shadows, contributing to their reinvention as a vocal harmony group.

Farrar's most significant impact came through his long-term collaboration with Olivia Newton-John from 1971 to 1989. He wrote and produced many of her hit singles, including "Have You Never Been Mellow," "You're the One That I Want," "Hopelessly Devoted to You," and "Magic." Farrar co-produced the soundtrack for the film "Grease" and was instrumental in Newton-John's success across multiple music markets.

In 1970, Farrar married Australian singer Pat Carroll, and they relocated to the United States in 1975. They have two sons, Sam Farrar, a musician with Phantom Planet and Maroon 5, and Max Farrar, a composer and producer. John Farrar's contributions to music, particularly his work with Olivia Newton-John, have cemented his legacy as a pivotal figure in the pop and rock music scenes of the 1970s and 1980s.
