All the songs on Supertramp's self-titled first album, released in 1970, were composed by Hodgson, Davies, and Palmer. Hodgson and Davies collaborated on the composing while Palmer wrote the lyrics. Palmer left shortly after the album's recording, allowing Hodgson to switch back to guitar (as well as providing keyboards with Davies). From their second album "Indelibly Stamped" forward, Hodgson and Davies wrote separately with each singing lead vocals on their own compositions. "Crime of the Century", released in 1974, was the first of their albums to feature the line-up of Hodgson, Davies and new members Bob Siebenberg (drums), Dougie Thomson (bass) and John Helliwell (saxophone, clarinet, keyboards, backing vocals).
