The song is called "Dirty Old Man." I have the words and music for it at home which I copied it from a Canadian folk music book I borrowed from the local library several years ago. I'll try to post the lyrics and chords tomorrow. If I remember correctly, it was written by Bob Ruzika (Ruzicka?) who, I think, hails from Edmonton. The only recording of it I've ever heard was by John Allan Cameron, probably on his Weddings, Wakes and Other Things Album.
