Watch AC/DC's Brian Johnson perform Back In Black with Foo Fighters

In the middle of a six-song set at Global Citizen's VAX LIVE: The Concert To Reunite The World, Foo Fighters brought out a very special guest in the form of AC/DC's Brian Johnson.

After tearing through All My Life and Everlong, Dave Grohl and co. invited the rock'n'roll legend out onto the stage to cover Back In Black.

"Who missed rock concerts?" Dave asked the crowd before introducing Brian. "You missed live music a little bit, right? Little bit. Me too! So considering that this is the first show that we've done in – I don't know – a year-and-a-half? A long time. We thought that we would make this a special occasion for all of us. Right?!

"So, say you wanna do something special, what do you do?! You call a friend to come play with you, right? That's usually what you do! Why not call one of your good friends – who happens to be a rock legend – to come jam with you? That's just what you do! So allow me to introduce you to one of our good friends who's gonna come up and do a song with us. Ladies and gentlemen: from AC/DC, Brian Johnson is here with us right now!"

GOOSEBUMPS!
