As many of us were basking in the glory of Coldplay last night, U2 were putting on a pretty sweet performance, too.

The band invited 50 London firefighters who fought in the Grenfell Tower blaze to watch them perform live in a private concert, which doubled as a rehearsal.

In a near-empty stadium, the firefighters watched U2 get ready for their Twickenham gig, and some took to Twitter to share their admiration for the band:

Really neat of U2 to invite firefighters and friends to rehearsal. Service people work so hard. Much deserved. #U2TheJoshuaTree2017

Invite to London Firefighters and their guests that was only confirmed very late yesterday evening. Very luckily I know a firefighter.

Bono and the lads played seven songs in total for the firefighters and their families.

Fair play, lads.
