Saw John Mayall live at Fabrik in Hamburg, must have been 20 years ago. Very polished. The support band were actually even more entertaining, as they had so much more energy and were obviously stoked to be supporting such a blues legend that the energy just pulsated out of them. Can't remember who they were now, maybe the Hamsters? Anyway cracking good gig.
I used to have Slim Harpo's "Tip on in" on 7" Single, on Excello label. I had a little box of 7" treasure that I foolishly lent to a mate for safekeeping. He thought I'd given them to him for keeps and swapped them for a broken air rifle! There was gold in that little box!
