On September 12 2007, promoter Harvey Goldsmith that the surviving members of Led Zeppelin would reunite for a one off show at London’s 02 Arena.

This show wasn’t just for the hell of it though. It was to honour the late Atlantic Records founder Ahmet Ertegun.

In the late John Bonham’s place playing drums was his son, Jason Bonham.

All profits from the show would go towards scholarships in Ertegun’s name in UK, the USA and Turkey, the country of his birth.

This concert was eventually released as a movie “Celebration Day”

According to Guinness World Records 2009, the concert holds the world record for the “Highest Demand for Tickets for One Music Concert” as 20 million requests for the reunion show were rendered online
