@ Judy Dyble - pleased to see mention of Derek Hall in your post of 13/2 - I used to see him a lot in the clubs around Reading (c'65/66), didn't know he had a London club residency; indeed, he was a very fine player - I have a much-treasured copy of the 'Out Of The Shades' EP he made, with Mike Cooper, & still love listening to the amazing work-out of 'Skillet' on that D28 he had ( he put in some stirling work on friend Cooper's 1st album, 'Oh Really?', too) - could never figure out how such a gifted player could seemingly just vanish, would dearly love to know what became of him..
