Co-wrote the song 'Beyond and Before' with Chris Squire and 'Sweetness' with Chris Squire and Jon Anderson, which both appeared on the first Yes album (incorrectly credited as Clive Bailey).
Founded psychedelic group Mabel Greer's Toyshop with Robert Hagger in London, England in 1967. The group evolved into Yes very soon after Bayley had left the group in July 1968.
