They've done it again....to a T! ;-)

So....you may have seen my post on the T-mobile flashmob TVC from a while ago. Well..they've done it again. This time they managed to gather around 14000 people in Trafalgar Square - people with no idea about why they were there. Throw in a few mics and a classic tune....and you have the worlds most amazing karaoke ad. Enjoy!
