(Incidentally, the best supermarket for music is Morrissons in Cromer, Norfolk - unusually light rock orientated, rather than crap pop stuff. Lots of Steely Dan. Yes, that was me grooving down Tinned Vegetables giving it "I've seen your picture ~Your name in lights above it", etc )
Anyway, as I was saying, I was at the checkout queue, still enjoying these sounds of the 70s, when someone asked the old dear behind the till the name of the particular tune that was playing. She didn't know. I looked up and said "Liquidator by The Harry J Allstars. I remember it from 1971." (yes, yes, I know, it actually came out in 1969). The "old dear" smiled at me (pityingly?) and said these words: "Oh, I wouldn't have known that, it was... before my time."
Much though I was terrified of skinheads in the early 70s, I did kinda like some of their music. So here's Liquidator.
