Pj Harvey was Dave Grohl's first choice to front Nirvana at the Rock and Roll Hall of Fame induction ceremony last week (ends13Apr14), but the British musician turned the opportunity down. The surviving members of the grunge group, Dave Grohl and Krist Novoselic, were joined on stage at the show by an all-star line-up of singers filling in for late frontman Kurt Cobain, including Joan Jett, St. Vincent, Sonic Youth's Kim Gordon and Lorde. Grohl has now revealed he initially asked PJ Harvey to take over vocals, but she said no due to scheduling problems. The Foo Fighters star tells Rolling Stone, "Kurt loved PJ Harvey. We had always imagined playing our song Milk It from In Utero with her. It's a twisted song, almost like something that could have been on her record Rid of Me, which was also produced by (In Utero producer) Steve Albini. It just seemed to pair up so well. Unfortunately, she couldn't make it." The rocker goes on to admit he came up with the idea of an all-female line-up of singers after Harvey turned the offer down, adding, "We thought, 'Wait, it has to be all women' Don't even ask anyone else. If we can fill the Rock and Roll Hall of Fame performance with these incredible women singing Nirvana songs, then we'll have achieved our own revolution.' It also added a whole other dimension to the show. It added substance and depth, so it didn't turn into a eulogy. It was more about the future." Grohl also admits the process was an emotional one for him: "The first time we played together, it was like seeing a ghost. The second time, it was a little more reserved. And the last time we played it was like that f**king Demi Moore/Patrick Swayze pottery wheel scene from Ghost... I hadn't played in that band in 20 years... I'd almost forgotten what it was like to be in a room full of Nirvana."
