I saw them onpril Fools day in 1985 just to say that I'd seen them. Their live shows and the whole 60's gypsy caravan was a neat experience, and the show was pretty good. They were a live band with the caveat that when they were having a good night, it would be a fun show, but when they were having a bad night they weren't so good. --Their studio stuff generally sucked.
--That being said, I'm sure that you know there is a collection of bootlegs from practically every Greatful Dead show at the Internet Archive site.
