Trevor Gordon was born in Blackpool, Lancashire, England in 1948 as Trevor Gordon Grunnill. He emigrated to Sydney, Australia with his family in the late 1950s. While still in high school, Gordon found work as a boy singer on the popular "Johnny O'Keefe" TV show leading to an exclusive contract with ABC, the Australian Television Network. This led to many live and TV appearances and Gordon was eventually made the host of his own Saturday afternoon kid's television program. During this time he met and befriended Barry, Maurice and Robin Gibb who were finding their own success in Australia as the Bee Gees. Gordon played lead guitar on several early Bees Gees tracks that appeared on the Bee Gees first album, The Bee Gees Sing and Play 14 Barry Gibb Songs. Gordon secured a record contract with Leedon Records and released the singles, "House Without Windows" and "And I'll Be Happy" (both songs written by Barry Gibb and credited to 'Trevor Gordon and the Bee Gees'), In 1965, Gordon recorded another Barry Gibb compositions: "Little Miss Rhythm and Blues" and "Here I Am".
Gordon returned to London in 1967, teaming up with his first cousin Graham Bonnet and eventually the pair became a musical duo called the Marbles. Not long after Gordon reconnected with his old mates, the Bee Gees, by now also in London and fast becoming international recording stars. The Gibbs helped Gordon and Bonnet secure a recording contract with the Australian record impresario, Robert Stigwood. Barry Gibb, Robin Gibb and Maurice Gibb wrote six songs for the Marbles and also provided some background vocals on their recordings, the most successful being the hit, "Only One Woman". With Bonnet's powerful vocals taking over the Marbles sound, Gordon felt under utilized and the duo soon disbanded. Gordon secured a contract with Polydor Records in London and released one album called Alphabet. Gordon was also a cast member of the Billy Cotton TV program in the UK before giving up performing and becoming a music teacher. In 1970, Gordon released his first and only solo album Alphabet on Polydor Records. He later became a high school music teacher. On 9 January 2013, after not being heard from for several weeks, Gordon was found dead in his London flat.
