The only thing I really remember from that concert, apart from being 20 feet from Clapton himself, was they played Let It Rain, just 3 acoustic guitars - Clapton, Dave Mason and I can't even remember who the 3rd acoustic was.
Apart from Dave Mason, who left soon after, it was the core Dominos, so yes, Gordon, Radle, Whitlock.
That year I also saw Ginger Baker's Airforce, with Graham Bond and Phil Seaman. And they were 2 hours late.
