(Undated) -- Coldplay's live debut of their Golden Globe-nominated hit "Atlas" didn't go quite as smoothly as they probably hoped. Frontman Chris Martin botched the start of the tune from "The Hunger Games: Catching Fire" soundtrack, and then played a bit of the Coldplay classic "Fix You" while he sorted things out.
Martin joked that they would edit the flub out for YouTube as the entire band gave "Atlas" a second and more successful try. The performance was part of Coldplay's "Under 1 Roof" charity concert in London last Thursday. The event raised money for the U.K. organization Kids Company, and also featured appearances from Lily Allen, Robbie Williams, and Ricky Gervais as his "Office" character David Brent.
