'Dance' reveals 400 people performing live at Liverpool Street Station where filming took place using 10 hidden data cameras. The dancers took to the floor in a whirlwind of choreography dancing to eight classic tracks from the 60s through to the 90s! The end result was a live dance-off taking place in front of the unsuspecting and dumfounded rush hour commuters, who had no idea they were watching or taking part in the new T-Mobile commercial.
