I just caught a piece of the concert on PBS the other night, too. They came out as a trio, and I assume they played the rest of the show that way, so I stand corrected regarding my prediction that they would add musicians.

However, I turned it off after the first two songs (I'm So Glad and Spoonful). If it had been nameless musicians, I wouldn't have lasted even that long. Unless they got much better as the show went on, I continue to feel that this was about nostalgia (for the audience) and money (for the band). The music didn't do much for me.
