As a teenager in the years just after WW2 I remember ex-servicemen singing a version of "I've got a lovely bunch of Coconuts" with totally different words to those being put out by the BBC on Billy Cottons Bandshow.

Also the lads who had seved in Egypt sang a version of the egyptian national anthem that started thus:-

King Farouk,King Farouk.hang your B*****Ks on a hook.....
