He may be one of the biggest rock stars on the planet, but Dave Grohl is still capable of holding a grudge.

The Foo Fighters frontman reunited with old schoolfriend Chet Lott at his band's gig in Memphis last week, and revealed to the crowd that he had been beaten in a Battle of the Bands competition by him when they were 15.

The pair covered Queen's 'Under Pressure', and it looked like there were no hard feelings by the end. Especially considering, as Lott put it to Grohl, 'I may have won the battle, but you won the war.'
