At last night's Valve party at GDC, a very interesting announcement was made during a game of Rock Band with Jonathan Coulton.

At around 10:00pm Jonathan took the stage. A bunch of us crowded up front, because we frankly have a bit of a man crush on him, and watched him run through his setlist. Right towards the end he announced he had only one left...

"I'd like to invite a couple of my friends up here to help me with my last song."

That is when we jumped on-stage and pulled out our Rock Band equipment piece by piece. Dan Teasdale (one of our senior designers) started picking a three person band with Jonathan and Alex Rigopulos (co-founder of Harmonix and head honcho). When they got to the song list they scrolled through an almost infinite amount of DLC until eventually they stopped on one-

"Still Alive" by GLaDOS

ALERT- THIS WAS A SPECIAL PREVIEW OF THIS SONG. IT WILL BE MADE AVAILABLE AS DLC AT A FUTURE DATE. WHEN I KNOW WHEN I'LL LET YOU KNOW. I NOW RETURN YOU TO THE NARRATIVE.

Yup. That is the song that Jonathan wrote that is the credits song at the end of Portal. The crowd went nuts. Earlier we had turned the backing vocals all the way down and the microphone vocals all the way up so we could actually hear his voice instead of GLaDOS. Alex was on drums ruling it, and Dan Teasdale held his own on guitar. By the end of the song even the people in the back of the room were screaming. It was an awesome way to debut a song we've been working on.

This is honestly the best news from GDC.  Whenever the song gets released, it isn't soon enough!
