From his Obit. in the Telegraph yesterday:

Rust’s own record collection was enormous, and contained several items of fabulous rarity. When his house was burgled in 1965, his remarkable memory helped to convict the thief. How could he possibly say, asked the defending counsel, that this particular copy of King Oliver’s Sweet Baby Doll was his? Because, said Rust, there was a tiny blemish on the surface which caused an audible click in the 17th bar of the third chorus. A gramophone was sent for, and the click sent the thief to prison for four months.
