I have previously sung the praises of the awesome game Portal and it's rather wonderful closing sequence, which I still smile about whenever I think of it...I haven't previously expressed how much I thoroughly enjoyed Felicia Day's geeky comendy The Guild or how chuffed I was that she mentioned The Clientele in an interview a while back. So...Felicia Day performing the Portal closing song with the writer Jonathan Coulton is the stuff dreams are made of - fortunately it was performed at a the sort of place so packed with geeks that there are stacks of videos on YouTube (and no doubt some were there within minutes of the performance)...this is (so far) the best of them...
