Wyatt was Chris Blackwell's first employee at Island Records London.
Trevor drove the Island cab, delivering records to the stores as well as taking the artists around when they came to town.
As such, he became a source of knowledge on who had recorded what in the studio and where their sessions could be found.
He was responsible for the Island Reggae Greats series of releases, and also found many alternate takes and demos for box sets by Nick Drake and Sandy Denny.
After the takeover by Universal Records, Wyatt followed Blackwell to Palm Pictures, where he worked for some years.
