Yes are an English progressive rock band that formed in London in 1968. Their music is marked by sharp dynamic contrasts, often extended song lengths, and a general showcasing of its members' instrumental skills. Yes uses symphonic and other so called 'classical' structures with their blend of musical styles in an innovative "marriage" of music. Despite a great many lineup changes, occasional splits and many changes in popular music, the band has continued for nearly 40 years and still retains a strong international following.
Yes was formed in 1968 by vocalist Jon Anderson and bassist Chris Squire. Anderson had already recorded a single in 1964 as a member of The Warriors, a beat band formed by his brother Tony, and later sang on a couple of 45s for Parlophone Records under the pseudonym Hans Christian. He was also briefly a member of the group Gun. Squire had been a member of The Syn, a flower-pop outfit who had recorded a couple of singles for Deram Records (one, "14-Hour Technicolour Dream", celebrating the "happening" held at Alexandra Palace on April 29/April 30, 1967). After the breakup of The Syn, Squire spent a year developing his bass-playing technique, strongly influenced by The Who's bassist, John Entwistle. Then, in May 1968, he met Anderson in a Soho nightclub, La Chasse, where Anderson was working. The two had a common interest in vocal harmony and began working together soon afterwards.
With Bailey's departure, Banks' return and the addition of organist/pianist Tony Kaye, the band became Yes. Banks came up with the three letter name, with the rationale that it would stand out on posters. The classically trained Kaye had already been in a series of unsuccessful groups (Johnny Taylor's Star Combo, The Federals, and Jimmy Winston and His Reflections).
