John Farrar ( /ˈfɑrər/; born on 8 November 1946 in Melbourne Australia) is a music producer, songwriter, music arranger, singer and guitarist who is best known for his work with Olivia Newton-John with whom he wrote and produced many hit songs.

Farrar is a former member of several groups including The Shadows, Marvin Welch & Farrar, The Strangers and The Mustangs. He is also the father of Phantom Planet bassist Sam Farrar as well as Golden Ghost guitarist/keyboardist Max Farrar.

Farrar began playing guitar when he was twelve, and by sixteen had begun playing with local rock bands such as The Mustangs.

Shortly after Farrar joined The Strangers, they became the house band for the popular TV music program The Go!! Show. Both Farrar's future wife, Pat Carroll, and Olivia Newton-John appeared on The Go Show as singers.

After returning from a tour with Newton-John, Carroll was obliged to return to Australia because her visa had expired, while Olivia (who was born in the UK) was able to stay on. Carroll dated and married Farrar. Following her marriage, Carroll ceased to pursue her headliner status and settled into occasionally reprising her duo work with Newton-John and back-up singing, mainly in session work for Farrar/Newton-John productions.

Hank Brian Marvin (born 28 October 1941) is an English guitarist, best known as the lead guitarist for The Shadows. The group, which primarily performed instrumentals, was formed as a backing band for vocalist Cliff Richard. Marvin has a distinctive guitar sound and appearance, primarily using a clean sound with very distinctive echo and vibrato giving a dreamy effect.

He was born Brian Robson Rankin on 28 October 1941 in Newcastle upon Tyne, England. As a child, he played the banjo and piano. After he heard one of Buddy Holly's songs, he decided to also learn the guitar.

He chose the name Hank Marvin while launching his music career. The name is an amalgamation of his childhood nickname of Hank, which he used to differentiate himself from a number of friends also named Brian, and Marvin Rainwater, a country and western singer.

When Marvin was 16, he travelled with his Rutherford Grammar School friend Bruce Welch to London, where he met Johnny Foster, Cliff Richard's manager, at The 2i's Coffee Bar in Soho. Foster was looking for a guitarist for Richard's upcoming tour of the U.K., and Marvin agreed to join as long as there was also a place for Welch. Foster had actually been looking for guitarist Tony Sheridan at the 2i's, but by chance he encountered Marvin. Marvin and Welch joined The Drifters, as Cliff Richard's group was then known, beginning their careers as professional guitar players.

George Harrison,MBE (25 February 1943 – 29 November 2001) was an English musician and singer-songwriter who achieved international fame as lead guitarist of The Beatles. Often referred to as "the quiet Beatle", Harrison became over time an admirer of Indian culture and mysticism, and introduced it to the other Beatles, as well as their Western audience. Following the band's break-up he was a successful solo artist, and later a founding member of the Traveling Wilburys. Harrison was also a session musician and a film and record producer. He is listed at number 11 in Rolling Stone magazine's list of "100 Greatest Guitarists of All Time".

Although most of The Beatles' songs were written by Lennon and McCartney, Beatle albums generally included one or two of Harrison's own songs, from With The Beatles onwards. His later compositions with The Beatles include "Here Comes the Sun", "Something" and "While My Guitar Gently Weeps". By the time of the band's break-up, Harrison had accumulated a backlog of material, which he then released as the triple album All Things Must Pass in 1970, from which two hit singles originated: a double A-side single, "My Sweet Lord" backed with "Isn't It a Pity", and "What Is Life". In addition to his solo work, Harrison co-wrote two hits for former Beatle Ringo Starr, as well as songs for the Traveling Wilburys—the supergroup he formed in 1988 with Jeff Lynne, Bob Dylan, Tom Petty, and Roy Orbison.
