Jeri, I did it when I finally realized that Coming Back to Miltown was the same tune as When the Works All Done Next Fall. Not really surprising, because many Irish songs came West, and got new lyrics.

There are also only really 16 notes, and a finite combination of those notes......so it is inevetible that something will sound like something else. I often hear relationships that no one else hears.....because I hear intervals, not notes.
