When I was a child in the early 1960s, I remember our family record player, fitted with a BSR GU4 deck, had difficulty playing one particular 45rpm single. It was "Tell Him" by Billie Davis. Dad fixed the jumping by sticking a twelve sided 3d coin on top of the arm. I still have that record and it plays reasonably well using a modern Shure magnetic cartridge.
