Grohl and co were performing a gig in Memphis, Tennessee on Wednesday (October 7, 2015) when he was joined onstage by Chet Lott, a classmate who had defeated the rocker in a music contest when they were 15.
So what did Chet have to say about it?
He announced on stage, “I may have won the battle, but you won the war.”
The pair performed a cover of Queen and David Bowie’s ‘Under Pressure’ (a Foo Fighters favourite!).
