Not to forget that the remnants of Asmans, after it closed, occupied the upstairs at Mole in later years. Saturday afternoons seemed to have (at least when I was there) a regular vintage jazz listening/critique session on the upstairs deck courtesy of 'mouldy figge' regulars.
The last time I was there though the Asmans desk was bare and the record deck was bust.
Also not forgetting 'All Change Records', next door to Sherlock Holmes's place on Baker St. They sort of morphed into Mole around 1978...
There was also that interesting avant-garde jazz shop near Neal St (pretty sure JohnS posted about this a while back), which didn't seem to last that long. Last time I passed the spot where I think it was located it looked to be a top end hairdressing salon.
The Camden Town store was my favourite - absolutely packed with good stuff. Jazz & reggae was their thing.
