I was also at that show. I do remember that the Allmans where the only act and that the show started sometime around 2:00 pm. As far as a set list I can only remember a few songs:
Statesboro Blues
Done Somebody Wrong
Les Brers
Midnight Rider
Hot Lanta
Stormy Monday
Barry Oakley was still alive but Duane was gone.
It was a great concert.
