I once drove a minibus load of twenty-something young ladies home after a New Year's Eve party. After some dubious drunken singing, they decided they felt sorry for me because I was driving and not able to join in with their revelries. Figuring, correctly, that I'd been a teenager in the 1970s, the proceeded to sing the whole of 'Tiger Feet', word perfect.
A week later, I spoke to two of them. "Do you still remember 'Tiger Feet'?", I asked. "What's that?", came the answer.
I'd also heard the entire life history of the great white shark that night, but I wasn't going to go there.
