Back in the day mid 70s, me and a mate named Craig use to go down to London about once every 3 weeks or so, It was my old nan god rest her soul that said why don't you go to portabello road theres lots of market stalls there that use to sell records, so we went down there and she was right about 20 / 30 stalls selling secondhand / used records, got tons of stuff that was massive at the casino, PJ Proby - you cant come home again - Liberty 10 copies. Bobby Goldborough, She chased me. 8 copies - United Artists
But the best finds were not on the market but in a tiny little shop that sold second hand clothes/ Bric-a-brac Stateside demos, Betty Everett I can't hear all nice r/w, Tamla motown demos The Originals, Goodnight Ireen g/w, all for 10p each, told a couple of other lads and they started to come down, Tom(Becket) on ss, and John washborne(washy) they couldn't believed we found the Aladins cave, tom came away with a load of Orielle stuff, Like gold dust in those days... In more resent times at car boots got the brothers - are you ready for this -rca, main ingrediant, Jackie Wilson early stuff on coral
I'd be lucky to find any 7" records of any kind these days at car boots, but they do turn up from time to time
