It's on the album "The Leprachaun" by a group called Sullivan's Gypsies", who I gather were (are?) a Canadian group consisting of Don Sullivan (bass, vocals), Garrett Kavanagh (vocals), Fergus O'Byrne (banjo, harpsicord, organ) and Dremot O'Reilly (lead guitar, mandolin, bass).

The album is on the Astor Gold Star Series (in Australia, that is) and I think I bought it about the late seventies.

It also has THE best version of Danny Boy I have ever heard.
