Last week we were front and center (or a bit off stage right, but whatever) for Foo Fighters private gig at Letterman. After doing much debate and thought, we realized the Foo's have played Letterman so many times and have all been memorable moments, especially their version of "Everlong" after Letterman's massive open heart surgery a decade ago. Take a look at some vintage clips and moments of the Foo Fighters on Letterman. Enjoy!
