I was there and enjoyed it much more than the rest of my camp. There was a lot of nonsense, but punctuated by Beatles songs regularly enough for it to be fine overall. Also, Bruce Springsteen (!!!).
World Premiere at BFI Southbank, with Edgar Wright intro.
(I was in the front row for this gig, and have a sore arm from Adam elbowing me every time he spotted me on screen)
