I saw Paul Dianno a few months ago....the Maiden songs were cool but he kept going on about how great punk is....to finish off the show they played Blitzkrieg Bop by the Ramones...he intro'd it by saying something like "fuck Maiden, fuck everyone else, this is a song by the greatest band ever"....when the crowd didn't get into it and sing along with the "Hey Ho...Lets Go" bits he had a little hissy fit and went "you don't even know the fucking words.....fuck this" chucked his mic on the ground and walked off
I guess the fact that his whole career is based off those first two Maiden albums (which he milks in his advertising, band logo and majority of his setlist) and 95% of the crowd don't give a fuck about what he's done after 1981...or about punk still hasn't occured to him.
I saw Pantera when Phil was so fucked up he could hardly stand...towards the end of their career. The band played well though.
