Flanders and Swann eh! I have both “At the drop of a hat” and “At the drop of another hat” in my vinyl record collection. Love the “Gnu song” especially, but “Gasman”, Hipopatamus song”, and the quite moving (at least to a railway enthusiast) “slow train” are great as well. Pure gold!
Funnily enough, I always thought Evadne and Hilda were based on Private Godfrey’s sisters Sissy and Dolly.....never thought about Flanders and Swann as role models...
