As I'm sure you're all aware Valve threw a little party during last week's big show (We weren't invited. I blame our butchering of their song.) and during the tail end of it they brought up Jonathan Coulton to play a set. At the end of his last song he invited the Rock Band folks up on the stage to play Still Alive on their game, a really neat way to announce that the song was coming to the game.
After they finished the crowd went crazy, a Harmonix developer told me the next day. The crowd was so excited, in fact, that one of them burst from the masses and jumped onto the stage. Walking up to the 360 that was home to the song, he plucked out a memory card, plugged it in and started fiddling. At which point one of their larger of the Harmonix guys walked over and asked him if he needed help with something.
"I'm just grabbing Still Alive, everyone needs to be able to play this", he said, if my source's memory serves.
The developer plucked the controller from the rotund man's hands and deftly deleted the song, which he had already managed to grab, from the card. Better luck next time.
The Harmonix guys thought it was even stranger that he later bragged to Harmonix co-founder Alex Rigopulos about it. Personally, I think it's super weird that he happened to have a Memory Card on him.
