It was at Winsford allnighter, and the acetate was of Walter & The Admerations. Butch walked from the record bar to the stage, took the needle off the acetate, took the acetate off the deck and threw it across the stage, then walked back to the record bar.
I wasn't the DJ, but I know who was, but I don't know whether he's on SS, so I'll not name him, but he's not local to Winsford.
