Pandemonium / Can You Forgive Her? - Live at the O2 Arena, London - 21 December 2009

This upbeat love song is about a lover who brings "chaos every time we meet."

Former Smiths and Electronic guitarist Johnny Marr plays both guitar and harmonica on this track.

The Pet Shop Boys originally wrote this song about former Babyshambles singer Pete Doherty's tempestuous relationship with supermodel Kate Moss and offered it to Kylie Minogue. However they ended up recording it themselves. Neil Tennant explained to Digital Spy: "It was originally written as a single for Kylie. About two years ago, we were asked in the same month to write songs for Kylie and Madonna. We wrote five songs for Kylie and one of them was 'Pandemonium.' Consequently the song's sung from a woman's point of view and I haven't changed the lyrics. It's sung from Kate Moss's point of view about Pete Doherty, but it's a bit of a cartoon version obviously."
