Yes, it's a fine song.  Unfortunately, it's been done to death by people who were too lazy, or self-important, to do the elementary courtesy of crediting it to the person who wrote it, and to bother giving it the title he intended for it.  Sure, they knew better, for wasn't it a traditional Irish song?  (irony)...

Adam McNaughtan, to give him his due, would be mortified by Guest Para Handy's comment.
