David Lloyd Stewart (born 30 December 1950) is an English keyboardist and composer known for his work with the progressive rock bands Uriel, Egg, Khan, Hatfield and the North, National Health, and Bruford. Stewart is the author of two books on music theory and wrote a music column for Keyboard magazine (USA) for thirteen years. He has also composed music for TV, film and radio, much of it for Victor Lewis-Smith's ARTV production company. He has worked with singer Barbara Gaskin since 1981. History Stewart was born in Waterloo, London. Having joined local covers band The Southsiders while still at school, Stewart's musical career began in earnest at the age of seventeen when he played organ in Uriel with Mont Campbell (bass, vocals), Steve Hillage (guitar, vocals) and Clive Brooks (drums). After a residency on the Isle of Wight in the summer of 1968, Hillage left the group to go to university. Uriel continued as a trio, later changed their name to Egg and subsequently recorded two albums for Decca. In 1969 Hillage briefly rejoined his former bandmates to record a one-off psychedelic album under the pseudonym Arzachel. In 1972 Stewart guested on Hillage's new band Khan's first album. After the break-up of Egg in 1973, Stewart joined Hatfield and the North, described by author Jonathan Coe as "probably the best-loved of the so-called 'Canterbury' bands". (Coe's novel The Rotters' Club takes its title from the band's second album.) Hatfield broke up in 1975 and, after guesting with the Steve Hillage-led Gong on a few French gigs, Stewart founded National Health with fellow keyboardist Alan Gowen and ex-Hatfield guitarist Phil Miller. Finding a permanent drummer proved difficult; Bill Bruford played with the group for a few months and was eventually replaced by Pip Pyle, thereby reuniting three of the former Hatfield musicians. Stewart subsequently guested on Bill Bruford's debut solo album, Feels Good to Me (1977), before joining his band Bruford. Having recorded three albums and played two successful US tours, the Bruford group was discontinued in 1980. Stewart immediately formed Rapid Eye Movement with his friends Pip Pyle (drums), Rick Biddulph (who had been a roadie and sound engineer for Hatfield and National Health) on bass and Jakko Jakszyk (guitar & vocals). The UK REM (not to be confused with the contemporaneous American band of the same name) was conceived primarily as a live band and never recorded an
