There was a phase for "Russian" songs at the time in CSH IIRC. One I recall had the lines

Sonya Sonya the law is at the door
(repeated twice)
Prussic Acid's in the wine!

And someone, possibly the Omsk song singer, use to introduce a song claiming it was called "The Russsian Steppes are cold and bare, they have no escalators".

Possible performers/writers of such items from names in my memory at that time include Curly Goss and a couple who sang at the Cellar called (I think) Zelda and Plonk! I wouldn't exclude Martin Winsor and Redd Sullivan from involvement either.
