Jonathan Coulton, producer, composer, performer and singer, as well as a just good guy, known for his iconic songs Still Alive from the Portal credits, have written in his Twitter that he has finished the main song of Portal 2.

"If this plane crash, then the song too. It's in my pocket "- he added.

Let's hope that Coulton is a good joker about a only single instance of the song, because physical media today have no respect. Also from this replica can be assumed that Valve has not yet completed production stage, at least its final part and credits.

Upcoming Portal 2 is planned for all major platforms in mid-April
