Dave Grohl was performing with the Foo Fighters in Sweden when he fell into the pit, severely injuring his leg.
The video tribute also includes Tre Cool, Chad Smith, Stewart Copeland and Max Weinberg.
Harley-Davidson enthusiasts Dave Grohl and Jay Leno will lead a procession of thousands of bikers before a live performance to benefit the Wounded Warriors Project.
But will it coincide with the recording of a new album?
“I was kinda imagining some sort of song in there, but I want you guys to be creative and think of your own thing,” said Foos drummer Taylor Hawkins.
Watch as Dave Grohl and the Foo Fighters pull out all the stops during their appearance as the final musical guests on the last-ever ‘Late Show with David Letterman.’
The final episode of the ‘Late Show’ takes place tonight (May 20), and additional special guests and appearances have been promised.
