This song was a big hit in Ireland about 20 years ago for the folk group, "The Wolfe Tones". It is still sung regularly at weddings, parties and the like and you will find it on any of the Wolfe Tones compilation albums. The version they sing has less of the South of England vernacular and is more understandable (and possibly more rude) to an international audience. Don't ask me for the lyrics - but I'm sure that there are some Wolfe Tones fans out there who will gladly oblige.
