Discussing the band’s 1997 hit ‘Everlong’, Grohl told Rolling Stone that even after decades of touring he still feels emotional when singing the fan favourite.
“There are nights where you’re thinking about what toppings are on the pizza on the bus and whether you need to do laundry tomorrow, but when you launch into a song like that, it immediately brings you back,” he said.
“We’re not robots. What chokes me up is when I see people singing lyrics back to me with the same emotion.
“So if you hear me kind of giggling in the middle of a song, it’s because I’m trying not to just fucking totally break down in front of everybody like a fool.”
In the interview, Grohl also discussed the one-off Nirvana reunion show in 2014, which marked the legendary band’s induction into the Rock and Roll Hall of Fame that year.
The footage featured the Foos frontman playing with former bandmate Krist Novoselic has long been slated for an official release, but Grohl is still unsure about its future.
“When we realised that we were going to do it, I just called the people from my production company and said, ‘We need to film this,’ and we loaded some cameras in there and shot it without knowing what would ever come of it… Someday, I’m sure everybody’ll see it,” he said.
“We talk about the changing of the guard when Nirvana’s ‘Nevermind’ came out and it really kicked open the door and kind of got rid of what people called plastic hair metal,” he said.
“The songs have endured and there’s no more alternative rock any more – we’re just a bunch of dads playing music now,” he added. “All of that has gone by the wayside”.
