I doing some research on some old music from 40's-50's and I came across Frankie Laine's Mule train.
There was a another perfomer who did it and whacked himself over the head with a pub tray whilst he sang it. I've got it on a Tommy Copper dvd but no name so I wonder if anyone can help me with it it.

Happy singing and tray whacking
