Worked mainly as a producer. After working for Chris Blackwell in the fledgling days of Island records Guy set up the (U.K.) Sue Records label which was exclusively devoted to bringing black American music to Britain and in the process turned a whole nation AND generation onto those sounds.
He was also the in house D.J. at London's legendary mod mecca in West Ham Yard, The Scene. Many a band (the Who included) traipsed over to Guy's pad to make tapes from his record collection (for a small fee) to cop material to cover.
When the U.K. Sue label finally was finished and mod was dead everyplace but in the provinces Guy tried his hand at record production working with ex-V.I.P.'s/pre-Spooky Tooth Art, ex-Action members Mighty Baby, Mott The Hoople and finally The Clash on their brilliant "London Calling" LP.
Sadly Guy died at just 38 shortly after his work with The Clash from an O.D. on a drug he was taking to help curb his alcoholism.
