Bizarrely, Daft Punk appeared to have won the festival without setting foot outside the backstage area: frankly, you wouldn't have wanted to be the band that had to follow their advert on stage. They whoop and cheer not merely the video for single Get Lucky but also the credits detailing its guest stars: Nile Rodgers, Pharrell Williams, legendary disco producer Giorgio Moroder, the Strokes' Julian Casablancas, veteran songwriter and film composer Paul Williams.

For another, there's the fact that the audience react as if Thomas Bangalter and Guy-Manuel de Homem Christo are performing unannounced live set. For one thing, there's the very fact that, in the middle of a festival, someone's opted to get their phone out and film not a band, or their friends, or the sunburnt man with his eyeballs pointing in different directions who's drawn a crowd outside the dance tent by stripping naked from the waist down and manipulating his genitals in time to the music, but an advert being shown on the big screens. If you want proof that Random Access Memories is, by some distance, the most eagerly anticipated album of recent years, then here it is. On YouTube, you can find cameraphone footage of an advert for Daft Punk's fourth studio album that was beamed out from the main stage at last month's Coachella festival.
