I would think there are multi-tracks of the L.A. Forum show, Atlanta night 2, and of course Passaic night 3. (Maybe others but we don't know)
This is a stunning release. I am obviously looking forward to more from 1980, but seeing as it's the least recorded tour I am sure we will have a wait. Interestingly, this show seems to honor Clarence on his anniversary as well as Doug on Father's day. (But alas, they dont do anniversaries!!!)
I predict a Devils and Dust show around July 9th or so, Maybe a River show in August.
