I do this song, but I have no idea who did it originally, or even where I learned it. The tune starts out like Alice's Restaurant. (C A DGC)

MY WIFE LEFT TOWN WITH A BANANA

My Wife left town with a banana Life's a rotten deal.
I found that yellow sucker just hiding in her purse,
He's cold and hard, but he's got appeal.
I hope it never happens to you,
Some fruit breaks your marriage in two.
My wife left town with a banana,
She slipped away.

My wife left town with a banana
Now I'm a jealous man.
She found a six inch latin lover.
Now she does the tango with her right hand.
Right now I could just die.
He's eating my banana creme pie.
My wife left town with a banana.
She slipped away.
