Arcade Fire played a prank on the Coachella audience on Sunday evening after bringing on two people dressed up in the gear Daft Punk wore to the Grammys in January this year.

The duo appeared to perform a slower version of the popular Get Lucky single but on closer inspection, neither were actually doing anything on the stage.
Consequence of Sound also claim the pair that appeared were not the same height and weight as the legitimate duo, Guy-Manuel de Homem-Christo and Thomas Bangalter.
At one point in the video, Arcade Fire frontman Win Butler can be heard asking: "What the fuck is happening?"
He is also reported to have referred to the masked men as "Phat Dunk".
A user on Instagram, Melissa Nguyen, wrote: "I think #arcadefire might've just #daftpunked us".
The duo were also apparently spotted wandering around the venue.
Television host Jonathan Ross also made an appearance on stage with Arcade Fire, which he tweeted about on Monday morning.
On stage with Arcade Fire at #Coachella2014 . Quite a night!
Neither Daft Punk nor Arcade Fire has officially commented on the appearance.
