Led Zeppelin shocked the organizers of their comeback concert with their list of backstage demands - because the requests were very simple.

The rockers - who will reunite for a special one-off concert on Monday - gave crew at London's O2 Arena a dressing room rider asking only for tea, coffee and an ironing board.

Harvey Goldsmith, the concert's promoter, says, "They've asked for cups of tea and coffee. We'll have some beer and a bottle of wine for them backstage but they have said they require very little. They are extremely focused and have been rehearsing. They know that a lot of people have been waiting a long time for this gig - it's going to be a great concert."
