The most amazing moment at a gig I have ever witnessed was when Ian Brown played the King's Hall in Belfast somewhere in the 2000s. A mate of mine had a spare so the two of us drove up. They had those plastic Stella bottles which we'd never seen in Dublin and to be honest never took off but they were great at a gig.
Anyway he comes on and starts chanting Georgie Best, Georgie Best to the tune of magic submarine which was all good but I think he dirtied his bib with one half of the community with something he said during his intro and I can't remember which side he insulted tbh so the crowd were a little on his back from the get-go and quite noticeabley different from Dublin the Belfast crowd were not taking any shit. So he starts into the first song and then he's not happy with the band so he stops them playing. So the boos start with gusto. The bad start playing again and as he's about to start signing he stops them again for some unknown fecking reason and by the third or fourth time this happened the aformentioned plastic stella bottles start flying up onto the stage. At one point a random girl in front of me turns around and goes 'I predict a riot'. That song hadn't been out too long at the time.
Browne takes umbrage with the bottle throwing and boo-ing and starts giving out. You couldn't make this up but he goes "if one more bottle comes up on this stage..." and as he is saying this we notice this bottle flying over our heads at the what looks like the right elevation and seems to be heading dead centre of the stage and toward Browne. Before he could finish the threat which was presumably to walk off, the plastic bottle of Stella smacked him right between the eyes. It was feckin hilarious. The whole crowd erupted in a massive 'ahhhhhhhh' followed by histerical laughter as he stormed off the stage.
The crowd were getting restless but still a bit giddy from the ridiculousness of it all. So eventually then some promoter dweeb came out to tell us that he'd agree to come back out but we were all to behave ourselves. So he came back out, no more messing, and it was great gig in the end.
