U.K. were a British progressive rock supergroup originally active from 1977 to 1980. The band was founded by bass guitarist John Wetton and drummer Bill Bruford, formerly the rhythm section of King Crimson. The band was rounded out by violinist/keyboardist Eddie Jobson, and guitarist Allan Holdsworth. Bruford and Holdsworth left in 1978, and Bruford was replaced by drummer Terry Bozzio. Jobson, Wetton and Bozzio reformed U.K. for a world tour in 2012. History Formation and first album John Wetton (formerly of Family, Uriah Heep and Roxy Music) and Bill Bruford (formerly of Yes) had worked together in King Crimson from 1972 to 1974, when guitarist Robert Fripp disbanded the group. In July 1976, Bruford assisted Wetton on demos originally proposed for a Wetton solo album (two of these demos were later released on the compilation Monkey Business in 1998). In September 1976, they formed a band with keyboardist Rick Wakeman, who had previously worked with Bruford in Yes. The project was stopped after rehearsals 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". Bruford and Wetton next approached Robert Fripp to reform King Crimson. When Fripp eventually declined, Bruford and Wetton decided that each would choose a musician in order to form a new band. Wetton brought in Eddie Jobson (formerly of Curved Air, Roxy Music and Frank Zappa’s band), whom he had met during his brief time as touring bassist with Roxy Music, thus "stealing" him from Zappa. Bruford recruited Allan Holdsworth (formerly of Soft Machine, Gong, Tempest and The Tony Williams Lifetime) who had played on Bruford's debut solo album, Feels Good to Me (1978). The band's formation coincided with the introduction of the Yamaha CS-80 synthesizer, and this instrument became an integral part of their developing sound. U.K. released their self-titled debut album in 1978 and followed it with a supporting tour. Following two lengthy American tours (June to October 1978), Wetton and Jobson decided to fire Holdsworth over musical differences, and since Bruford had indicated to Wetton that he would favour Holdsworth’s more improvisational approach in the event of a disagreement on the direction of the band, they lined up Terry Bozzio (another one-time Frank Zappa band member) to replace Bruford. Bruford took several instrumentals with him that he had developed for the live U.K.
