To be fair, Back in Black would be awesome. I just watched Nice Boys from this show and Axl was in full AC/DC mode on that one, although I doubt most of that crowd will even know who Angus Young is. The last time I watched anything to do with Glastonbury was when Metallica headlined 9 years ago and their shows are usually about 2 hours anyway. Hopefully they stretch it as far as they can as even a heavily stripped down set is well over 2 hours.
