It is the show some fans have waited two decades to see - and last night dreams were realised as Led Zeppelin rose again in London, playing almost two hours of their most famous songs.
Robert Plant, in jeans not quite as famously tight as they were 27 years ago, still had the energy to strut his 59-year-old body across the stage. Guitarist Jimmy Page, 63, and bassist John Paul Jones, 61, kept a less energetic pace with him.
As the band settled into a series of songs old and new, grown men in the mostly middle-aged and male audience began playing air guitar.
Some of the old Zeppelin remained, during a monumentally long instrumental. Plant had time to go off stage as Page continued to play with dry ice fumes swirling about his feet.
Some 18,000 people were at the O2 arena to witness the comeback, travelling from 50 different countries. (Sky News)
