U.K. were a short-lived British progressive rock supergroup active from 1977 through 1980. In September 1976, singer/bassist John Wetton and drummer Bill Bruford, alumni of King Crimson, worked on forming a band with Yes keyboardist Rick Wakeman. The project was stopped by Wakeman’s label. According to Bruford, “A&M Records were unwilling to let their ‘star,’ Wakeman, walk off with a used, slightly soiled King Crimson rhythm section, and the idea failed.”
