Billy Corgan falls down

Naturally, when Billy Corgan swoons on stage, he doesn't just swoon. He emotes as he collapses:

"For those that saw me fall last night during 'Bullet [With Butterfly Wings]' that wasn't a stage move or clumsiness," Corgan wrote on his Twitter page - Twitter.com/Billy. "That was me blacking out and wiping out."

He added: "I have no memory of falling against the drum riser and my guitar cabinet, but I can tell you I've got quite a good bruise + am moving slow."

Doctors report that it's likely that the sheer intenseness of Corgan's intensity might have caused his brow to be come intellectually over-furrowed, cutting off the flow of pure muse to his central self-belief.
