They got good distribution here in the early batches - the one with the Fats Navarro, Coltrane ‘Countdown’ and Byrd ‘Long Green’. I guess the damned accountants latched on before those later issues came out, so they then became a more elusive US import. Early 80s oil shock can’t have helped either. The ones over here were the EMI Electrola I think, very good sound too.
Mole, HMV etc. had many of them in the deletions bin. Happy days !
I still have all of the ones I bought and pick up the US ones when I come across them. I have the ‘Black California Vol 2’ I think.
