Anon was one of two bands made up of pupils from Charterhouse School in Surrey, members of which went on to form the progressive rock band Genesis with another band from the same school, called Garden Wall. The band formed in May 1965 and split up in December 1966. It originally consisted of Rivers Jobe (bass), Richard MacPhail (vocals), Anthony Phillips (lead guitar), and Rob Tyrell (drums). They were later joined by future Genesis guitarist/bassist Mike Rutherford on rhythm guitar.
