I'm sure this is a "borrowed tune" but I'm so used to hearing this song now that I can't easily think of the original.

Assuming I'm correct, can anyone help out?
It's actually a very nice melody but I'd rather not sing or play "Star of the Bar" itself as, while it is a "classic",

a)it is already ubiquitous and, arguably, oversung
b) it is more suited to a "macho male" type of performer as opposeed to a sensitive, caring "new man" such as myself.
