WATCH: Grohl Joins McCartney On Stage For “I Saw Her Standing There”

Fans at the Paul McCartney show at London’s O2 Arena this past weekend got quite the surprise when Dave Grohl decided to stop on by and join in during “I Saw Her Standing There.”

McCartney is currently on his “Out There” tour, while Grohl was in town with the Foo Fighters for their current “Sonic Highways” world tour.

You gotta love two touring schedules collide and help create cool moments like this! We, personally, can’t get enough of these fun live surprises like this!
