In May 1968, Barrie introduced Anderson to Chris Squire, bassist of the London-based rock band Mabel Greer's Toyshop, which had previously included guitarist Peter Banks. The two talked, and found they shared common musical interests such as Simon & Garfunkel and the idea of vocal harmonies. In the following days, they developed "Sweetness", a song later recorded on the first Yes album. Anderson found himself on lead vocals for some Mabel Greer gigs afterwards, and talks of the formation of a new, full-time band developed. In June 1968, Anderson and Squire hired Bill Bruford to replace founding drummer Robert Hagger, and Anderson secured £500 from John Roberts, owner of a paper manufacturer, to rent space in The Lucky Horseshoe cafe in Soho so a new, full-time band could rehearse. At their conclusion a month later, a line-up of Anderson, Squire, Bruford, Banks, who replaced a departing Clive Bayley, and keyboardist Tony Kaye, who Anderson met in Leicester four years prior, was formed. They then renamed themselves Yes, originally Banks' idea. Anderson's first gig with Yes followed on 4 August 1968 at a youth camp in East Mersea in Essex.
