On Friday night we were lucky enough to witness a pretty special event: geek-rock troubadour Jonathan Coulton performing his song "Still Alive" at San Francisco's Great American Music Hall. There's nothing new about that, he's been performing it since Portal's release last year. What is new is that he was playing it in Rock Band, where it's due to be released as downloadable content, and we just so happened to get it all on camera.

Unfortunately, most of Coulton's Rock Band band wasn't quite up to his level, with the lone exception of ... hey, it's Mahalo Daily's Veronica Belmont, who you should recognize from her GDC videos here on Joystiq.

One of the Harmonix folks there told us the track was only in production for an unusually short six weeks, thanks in no small part to Valve's willingness (you might even call it eagerness) to license the song. They also said that, though nothing has been finalized yet, they're expecting the track to be attractively priced at $0.99 leaving you no reason to avoid it. High-def video embedded after the break.
