I didn't know about Donna singing backup for Elvis, but I sure did know about Ron Tutt touring with Elvis. Great drummer.
I'm working my way through the set. "Dark Star" isn't one of my Dead benchmarks. I'm really enjoying the Pigpen on this set. I usually don't go nuts for Pigpen, but when he's really "on" and the boys feel like playing behind him, magic happens. Magic happens on some of these numbers on this set too because they get the tempoes just spot on.
And I always scratch my head whenever they play "Doin' that Rag." Do they ever play that tune as if they really really really knew it?
