Thanks guys.
Two of my friends got together one night when their wives where away and watched some old black and white John Wayne movies on DVD.

He still may have been know as Marion Morrison then?
My friends reminded me of two young boys let lose for the first time.

One being in his mid sixties and the other pushing forty.
Their telling of the night out amused me so I wrote the tune from their get together.

From memory I don't think they really used cap guns?

Thanks again.
Rob
