The last time I saw Maiden in Cleveland, it was an outside show, it was hot, and the crowd was getting pretty obnoxious. One group, in particular, were getting a bit out of hand. Well, about 2/3 of the way through the show, Steve was out front, foot on the monitor, giving his energy out to the crowd, and this frackin' idiot throws a full cup of beer (and I am talking Big Gulp sized) at Steve, soaking him and his bass (I think it was the white one). I swear to God, I thought Steve was going to jump out into the crowd and rip the guy's throat out with his bare hands!

He was as pissed as I have seen a man get, and Bruce had to physically restrain him. He kinda threw the bass down (and someone grabbed it before it hit, I think it was Bruce, again, who was really on top of things and trying to control the situation), and then charged towards the stage. After a bit, he stormed off, and I thought that this was the end of the show.
After some time of awkward silence - and near rioting in the crowd - Bruce suggests to the audience that 'the next time a guy brings his arm back with the intention of hurling a beer at the stage, you ought to make sure that he is not able to complete the motion.' The crowd goes nuts, and after some improve drum and guitar work, Steve comes back out. Still pissed. It probably took him a song and a half to get back into the groove, but once he did, he did so with even more vigor and gusto.
I am still disappointed and saddened that such idiotic behavior was exhibited at a show in my home state, but it certainly made for a memorable experience. Dickinson was amazing, and I'll never forget how well he handled that situation.
