I remember once seeing Sam Larner sing B&C&A at Ballads & Blues in Princess Louise days. He not only made a great long monologue of "You know what old women are, don't you? You know what they're like, har har har", &c - he actually made a sort of production of taking out his false teeth & putting them in his pocket before beginning the song, saying "Ah, that's easier — this is that sort of song where you need to feel easy, you know." Only time I ever heard him live; it must have been about 52 years ago but I have never forgotten it.
