Hmm... guess I'd just have to say "Well, it looks like I found out why you're called Doctor Steel then eh?"
The "band" before that would be the Red Army Choir... I don't know the actual singer of it so I guess Stalin? Or a legion of manly Russian soldiers/vocalists? 0_0 That sounds both awesome and incredibly terrifying at the same time...
Before that was a Team Fortress 2 Remix with the Soldier "singing" it.
And before that would be "Voltaire"... That would be awesome if he didn't already have a wife and kid.
