The War On Drugs got a little help from Questlove on their Fallon performance last night. The band blasted through 'Baby Missiles' with help from the Roots' man on secondary drumming duty. Don't worry, it wasn't like some sort of Jools Holland 'boogie woogie over everything' typer collaboration - just a strong performance from everyone involved.

The track is taken from the beautiful Slave Ambient. You can find out about their new single here.
