T-Mobile's latest ad from Trafalgar Square

Today T-Mobile filmed the next part of its 'Life's For Sharing' campaign in Trafalgar Square, London. As word quickly spread, thousands of people arrived to try to get their share of the lime light.

By all accounts, Trafalgar Square was turned in to a big karaoke party, with the crowd singing along to music from films such as The Blues Brothers and Grease and other classics such as 'Total Eclipse Of The Heart' by Bonnie Tyler.

There's a chance the ad may be turned around as quickly as this weekend so keep an eye out for friends, family or colleagues who may have played their part!

Here's the previous ad for anyone who may have missed it?

It's great to see a brand galvanise such energy, enthusiasm and most importantly, interaction from the public. It's a prime example of how companies should be looking to move forward with their marketing and take advantage of the recent advances in technology.
