Britain's Got Talent 2012 auditions: The Zimmers surprise with a rap!

The Zimmers (Britain's Got Talent 2012)

The Britain's Got Talent 2012 auditions tonight saw the world's oldest band, The Zimmers, who had a combined age of around 3,000 years.

The group first got on the wrong side of the judges as they shuffled on stage and then took absolutely ages to finally get around to starting their act.

But when the group of OAPs stripped out of their coats and donned baseball caps, the judges suddenly sat up.

What followed was a rap from the group, with Simon calling one of the panel a "little tiger"

Host Dec remarked: "I've never seen anything like it."

Alesha told them: "That was so inspiring, it was brilliant."

It was four yeses from the judges for The Zimmers!
