Just been looking for the lyrics myself my parents and all there friends used to sing this when they got a bit merry. I think it a typical song of the era where teenagers didn't buy a record but the sheet music and all band together for a singalong. hence why everyone has different lyrics (I not remember my parents one being quite so rude but i do remember being shocked!"
Anyway thank soft the helping my memory I think when i next call home i will ave to ask my parents (now in there 70's for the lyrics).
