Jason Crest

Jason Crest (formerly The Good Thing Brigade) were a Tonbridge, Kent based psychedelic pop group, active from around 1967 to 1969. Despite releasing five singles on Philips from 1967 to 1968, (including a cover of The Move's (Here We Go Round) The Lemon Tree), the band were never commercially successful and disbanded towards the end of 1960s when their contract with Philips expired.
