:-). I like to group song versions under one heading and call them all varients of that group. I'm a grouper. But this song group is a good example of when it can get silly to try. Cross-reference, yes, but not equate. As John says, sometimes it only makes sense to look at the verses. This is what Sam Hinton calls a "wandering folksong." And what television producers call "an all-new situation comedy."
