"I'm a bit of a stickler for tunes"

I'm pretty sure that in past threads you've told us that you often improvise tunes. And tunes and words go together, so my comments weren't entirely off topic. And my original point remains - Everyone changes songs, and there's no point in singing folk songs if you're not trying to make them your own. Why slavishly recreate someone else's work? They have paint-by-numbers if you like that sort of thing.
