The Pet Shop Boys do their greatest hits in 10 minutes at the Brit Awards 2009, along with Lady Gaga and Brandon Flowers!
[Update 22/02/09] Apparently this medley was produced by Stuart Price aka Jacques Lu Cont, but I need to verify that somewhere. You will get the audio of this a bonus track if you pre-order their new album Yes on iTunes.
[Update 25/03/09] Oh, the joy of Twitter. I asked the Pet Shop Boys if Stuart had helped produce the Brit medley. They answered, “Yes”, although that could just have been a plug for the new album!
