David Letterman ended his incredible 33-year run as a late-night host yesterday, and as previously reported, the Foo Fighters were on hand to help him say goodbye.
The Foo Fighters started their week-long residency on 'Late Show With David Letterman' by paying tribute to Black Sabbath, but for their second night, they stayed much closer to home, teaming up with Heart for a rendition of the Seattle legends' 'Kick It Out.'
