The financial dimension always plays into it, but because the endeavour is so expensive in general, I don't see that as a likelihood. It would still likely be needing at least two of those superstars to drop prices or have a festival affiliation - see; Neil Young.

Interesting, as I think it is his first "great" album, even if there isn't quite the larger depth of out-and-out bangers yet.
I think he's had a few issues picking his choices live too. He hasn't quite nailed the specifics of picking the best live songs sometimes.
