Gerry Rafferty was a popular music giant at the end of the '70s, thanks to the song Baker Street and the album City to City. His career long predated that fixture of Top 40 radio, however; indeed, by the time he cut Baker Street Rafferty had already been a member of two successful groups, the Humblebums and Stealers Wheel.
Rafferty was born in Paisley, Scotland in 1947, the son of a Scottish mother and an Irish father. His father was deaf but still enjoyed singing, mostly Irish rebel songs, and his early experience of music was a combination of Catholic hymns, traditional folk music, and '50s pop music.
By 1968, at age 21, Rafferty was a singer-guitarist and had started trying to write songs professionally, and was looking for a gig of his own. Enter Billy Connolly, late of Scottish bands like the Skillet Lickers and the Acme Brush Company. Connolly was a musician and comedian who'd found that telling jokes from the stage was as appealing an activity to him -- and the audience -- as making music.
He'd passed through several groups looking for a niche before finally forming a duo called the Humblebums with Tim Harvey, a rock guitarist. They'd established themselves in Glasgow, and were then approached by Transatlantic, one of the more successful independent record labels in England at the time, and signed to a recording contract. After playing a show in Paisley, Rafferty approached Connolly about auditioning some of the songs he'd written. Connolly was impressed not only with the songs but with their author, and suddenly the Humblebums were a trio.
