You've missed out one of the verses, I don't remember it word for word but it ends thus -


...strummin' themselves wiv three chords only.
Once we danced from twelve to three
I've got news for Elvis P
Fings ain't wot they used t'be

..oh, and don't take the piss out of Max Bygraves...there won't be many of US who will be as well-loved and well-remembered when we are in our eighties.....
