The song was written by Charlie McGettigan from Co Leitrim in Ireland, who among other achievements was a member of an excellent group called Jargon based in the Sligo/Letrim area, and won the Eurovision Song Contest as a duet with Paul Harrington singing The Rock & Roll Kids.

I don't know if he has a web-site but its probably worth checking. The song has been recorded by a number of others including Maura O Connell and probably Eleanor Shanley.
