I remember years ago there was a radio show by Billy Butler and Wally Scott on local radio in Liverpool. Part of the show was a general knowledge quiz titled "Hold your plums" One time it was a question on "The Lion sleeps tonight", anyway Billy asks the lady contestant the name of the group that sang it, she gave many wrong replies, and finally was told that she would have to hurry up, she asked for a clue, Billy told her to think of her husbands underpants, she thought for a while and then said is it the Dooleys? Mr Butler couldn't stop laughing. (The answer was Tight Fit!!!)
