My mother was a keen watcher of the B&WMS in its day, on account of Dai Francis (the Welsh baritone).
My mother walked in from the kitchen one evening to see Dai Francis (in civvies, as it were) on a chat show. She didn't realise it was Dai Francis because a) he wasn't singing at that point and, b) he wasn't blacked up. Towards the end of the show he burst into song and my mother said what a brilliant singer this fella is.... he sounds just like Dai Francis! My Dad howled with laughter.
Aye, different times.
