Oh, I think we'd still get new information; we'd also still get people repeating what has already been said because they couldn't be bothered to read what was already there, though. That's annoying when you've spent time and effort providing comprehensive information and references, of course, but not as annoying as when people repeat misinformation which has already been dealt with; and that's just as common, and unnecessary.

All that business about horns has been pretty well talked to death, for example. Why go over it all again, and silt the Forum up with more repetition? I'd be surprised if there was anything useful to add, though I'd be pleased to hear something new on the subject. So long as it really is new; I don't think that recordings by Revival performers are likely to add to our understanding of this song, as they're removed from the living traditional context where its significance extends beyond the words and the music and it has a specific social function.
