'like arguing over the 4th word in the 3rd line of the 126th verse of "Barbara Allen."'

I opine you meant to say the 3rd word in the 4th line. It can be found as Child Ballad 84 and Roud 54. There are at least 90 versions of the song.

Spaw knows them all; that's why he screws up the number. Ever since we taught him to count he's been adding things. Thus the reference to verse 126 which, as we're aware, doesn't exist. As for Rap, he's a trumpet player so we cut him a bit of slack.

As for music talk, Semo, that usually takes a more scholarly tone Above the Line or Above the Salt (don't ask). Basically, they are music threads and they are reserved for music talk where people remain polite and friendly, even if they think the person they're speaking with has his head where the sun don't shine because it's dark as a dungeon, etc.

To give you an idea, Spaw will likely have something to say about this image. He will suggest a few ways to make a musical instrument out of the empty tin. He would never do that above the line. He's been touchy ever since the successful reducing operation he had done on his pecker. Before the surgery he was part of the Olympic pole vaulting team, their guiding spirit as it were. But that's another story.
