OK, here's a short review:
Went with my sister (she hates them but nobody else would go with me and I couldn't waste the other ticket). First support band - don't know who they were, sorry - weren't bad but the second lot were awful. As was the wait between them and BRMC - three quarters of an hour! The main attraction finally came on at 11 and it was, for me at least, pure bliss from there on in. The boys did good! :D
Biggest bummer of the night: having to leave two songs before the end to get a lift home. Liam and I didn't get to meet up, either (he did try looking for me, though). I was actually quite surprised when he told me he didn't enjoy himself - it was the night of the year for me and I don't think anything could possibly top it.
