Apart from a token Bon Jovi track, there weren’t many songs that inspired a massive group singalong. Except one.

You put Rock Band in a room full of geeks with a full track list and there’s one song that everyone is turning to. “Still Alive”, The theme from the ending of Valve’s dimension bending masterpiece “Portal”, had us all crooning with class and we finished with huge smiles on our faces.

Written by Jonathan Coulton and a favourite amongst gamers everywhere, it’s lyrics are sublime and the music is crafted by angels themselves.

Here’s Jonathan and Felicia Day (her of Buffy fame), singing along at the PAX expo in 2008. God bless them and New Years can’t come soon enough for an encore.
