Queen 2012 Olympics Closing Ceremony Performance- Video:

Twenty seven years ago, Freddie Mercury electrified thousands of spectators at the Live Aid concert at Wembley Stadium in London.

On Sunday - 20 years after his death - the late Queen frontman did the same again - with the same performance - belting out "d-ey-o, d-ey-o" from a giant screen to an 80,000-strong crowd at the closing ceremony of the London Games.
