“When I sing along with you/ If everything could ever feel this real forever/If anything could ever be this good again/The only thing I’ll ever ask of you/You’ve got to promise not to stop when I say when.” This song was released three years after Kurt Cobain’s death, and it certainly felt like it could have been about him. Dave Grohl allegedly wrote that about an ex-, but, as we’ve mentioned, universal lyrics transcend their original inspiration, and that’s certainly true here. It also clearly has a lot of meaning to David Letterman: in 2000, after the talk show host had quintuple bypass surgery, he said that listening to “Everlong” was crucial to his recovery. For his first show back after the surgery, Letterman asked the band to come on the show and play that song. The Foo Fighters often close their shows with this song, and — of course — the audience sings along with Dave. Many of them surely have their own stories too, and it’s always a powerful moment.
