A clarification for younger readers - no, this is not the Darkness wandering backstage after a gig in the 2000s, it's Led Zeppelin at Madison Square Garden in 1977. We're not convinced Jimmy Page should be smoking that cigarette in an outfit that looks like it would go up in flames at the drop of a hat, and is it us, or is Robert Plant picking his nose very happily as he walks along behind him?
The tour this picture was taken from were pivotal moments for Led Zeppelin. They were on the comeback trail after missing 1976 completely when Plant was severely injured in a car accident. At the time, they were the biggest band in the world, and the timing couldn't have been worse. The tour, however, was a huge success, and the band reclaimed their crown immediately.
