Jan Dukes De Grey was a progressive-folk band, and only released two albums in their short life span. Jan Dukes De Grey formed in 1969 and were one of the very last prog rock bands to be signed to Decca's prog label. They originally started out as just a duo and were rivals to glam-rock band T Rex. Their first album, "Sorcerers" was a typical acid folk album, not particularly adventurous but showcased Derek Noy's and Michael Bairstow's multi-instrumental talents. The album made little impact and is only available through bootleg.
