Theft is a good old American tradion. Beides, it's not theft. It's the ORAL TRADITION. Joe Hill did it. Woody did it ALL THE TIME. Many of us (me for sure) have used "better" taditional tunes for a song than the "boring" tune we found it with. It was a way to set ourselves apart from another person's rendidion---and to make, in our opinion, a better song. Very little is EVER really original all the way. By using another traditional tune for an already traditional set of lyrics, we keep it a traditional song (and avoid royalties & copyrights).
