The tune can be found at the link above in a variety of formats. If you read some of the other threads, you will find some conflicts on the tune as to whether it is or isn't a traditional tune. It's difficult. If you look at the message from GUEST on July 02, 2001 and the message from Rossey from July 01, 2001, you will find probably the most specific information on copyright for the tune and song.
