Arcade Fire like to spring a few surprises.
The Canadian group recently completed a North American tour, culminating in headline slots at Coachella. At the first leg of the desert festival, the band invited Blondie singer Debbie Harry onstage for a rendition of 'Heart Of Glass'.
The second leg took place at the weekend, with Arcade Fire helping to close the event. Inviting two people dressed as Daft Punk along for the ride, the show was introduced by none other than British talk show host Jonathan Ross.

Of course, that wasn't the only guest appearance of the weekend. Green Day's Billie Joe Armstrong guested with The Replacements, but sang his part from a sofa after injuring his back.
