It originally consisted of Rivers Jobe (bass), Richard Macphail (vocals), Anthony Phillips (lead guitar), and Rob Tyrrell (drums).
During a short period of time, Rutherford was forced to leave the band by his house master at Charterhouse and was replaced by Mike Colman.
The Spiders had been a Beatles type band, and when Phillips entered Charterhouse in April 1965, he hooked up with his old friend and formed Anon with Rob Tyrrell and Richard Macphail within a week.
Anon was dedicated to covering songs by the Beatles, the Rolling Stones, and rhythm and blues music from that era, like John Mayall.
Phillips and Rutherford then went on to join with all three members of Garden Wall (vocalist Peter Gabriel, keyboardist Tony Banks, and drummer Chris Stewart) in 1967, to form Genesis (with Mike buying his first bass), in January 1967.
