Arcade Fire were guests on BBC Radio’s Live Lounge this week, where they brought along a youth choir for backup.

Bringing the title track from their forthcoming record, Everything Now, the influential indie group also covered Lorde’s recent Melodrama hit “Green Light.” You can listen to the entire performance on the BBC radio player, or through a snippet posted to Twitter below. The full version is expected out later this afternoon.

Arcade Fire also taught the youth choir words to “Everything Now” where they jammed out to it in the Live Lounge.
