Sarah Grey has a US version of Mathy Groves (I think) where Lord Darnell, having bumped off MG with his sword, sees off Lady D with his Police Special! The sneaky little page was none other than Robert Ford!

There's an excellent Black Country version of the song, set in Dudley. To my shame, I can't remember the name of the man who wrote it. The two men have at each other in good ol' (Teddy-)boy style with bicycle chains:

It's true as I've got two bike chains
I got 'em off me mate;
But yo' can 'ave the 'alf-inch,
An' I'll 'ave the three-eight!

If anyone can tell me the rest, I'll be dead chuffed. I think this song & its variants deserve a thread to themselves (there probably is one, I haven't looked).
