Keith Alan Hopkins, better known by his stage name, Keith West (born 6 December 1943, Dagenham, Essex, England) was the lead singer of Tomorrow, a 1960s psychedelic rock band. West composed most of the band's songs (duly credited to Keith Hopkins). Despite critical acclaim and support from BBC Radio 1 DJ John Peel, who featured them on his Perfumed Garden show, the band was not a commercial success.
In 1964, West became lead singer of "In Crowd" a rock band from London, which was then renamed Tomorrow. Another member of that earlier band was the guitarist Steve Howe (later Yes). In 1967 West became acquainted with Mark Wirtz, a producer who had already created the instrumental title, "A Touch of Velvet, a Sting of Brass" (1965). Later on, the melody became the theme music for the German television programs, Beat-Club and Musikladen.
West himself is perhaps better known as a participant of Wirtz's A Teenage Opera. He was the singer of "Excerpt from A Teenage Opera", also known as "Grocer Jack", which reached #2 on the UK Singles Chart in 1967. He also performed "Sam," which reached the bottom end of the UK Top 40 the same year.
