How TV Ruined Your Life

Does anybody know what the piece of music is that was used during and at the end of the last episode of Charlie Brooker's How TV Ruined Your Life?

Any help would be much appreciated.

It's a cover of Sex Pistols' 'Pretty Vacant' by the London Punkharmonic Orchestra:

And very good it is too.

On a similar note, can anyone tell me the name of the music played at the very beginning and over the end credits of episode 1? Probably something really obvious but it's driving me nuts trying to put my finger on it.

Ah brilliant, thanks! Knew it seemed familiar!
