It doesn't belong on Mudcat, IMO. Kendall Morse went once in recent years, and probably occasionally earlier. Mick went once. I wasn't involved then, Linn is likely aware of the query from years ago, Jerry Rasmussen!?, and I believe this is being handled CORRECTLY elsewhere.
The guy wants to know about the Dylan years. I suspect the guy has tapes the festival folks are trying to get, or wants tapes (I sort of remember this coming up elsewhere), but it's definitely not a question for Mudcat and the entire frickin' world. There are folks on Facebook who might answer there.
