Family legend has it that one of my mother's, very prim and proper,aunts who didn't drink- but sherry didn't count- had too much at a family gathering (wedding or funeral) and suddenly in a moment of hush sat up, said, with her hat cocked over one eye: "I'm going to sing Bonny Mary of Argyll" and did so to general amazement. Saying passed into family folklore for someone getting up to perform!
