Written by Mike Cross and joyously recorded by Bryan Bowers circa 1980. How come nobody does anything like this these days? Is it out there ? Am I missing out?
There's lots of good Celtic/folk music out there with that kind humorous theme; drinking music has a lot of that. Australian
"The Bushwackers" and Canadian
"Tanglefoot" folk music often has subdued or off-color humor. True, too of maritime music.

Clancy Brothers and Tommy Makem, The Wild Colonial Boys, The Fureys and Davey Arthur, humor usually associated with a pub setting.
