Dave Grohl wanted PJ Harvey to sing a Nirvana track with him when he brought his Sound City Players supergroup to the UK.
The musician played with the surviving members of the band, Krist Noveselic and Pat Smear as part of his Sound City Players supergroup, and approached PJ - short for Polly Jean - to sing one of his old band's songs in place of Kurt Cobain.
He said: ''Someone came up with the idea of doing a Nirvana song with PJ Harvey. Kurt loved her and we love her and we thought 'Yeah, what would we do?' I said, 'God, what if we were to do 'Milk It' from 'In Utero' with Polly singing.'
''We all looked at each other like, 'Whoa, that would be amazing.' And then she couldn't do it!''
Dave added he's always been wary of playing the songs of Nirvana live since Kurt's suicide in 1994 as they have gone on to have such legendary status in musical history.
He added to NME magazine: ''It's sacred ground. If we were ever going to so something like that it would have to be right, because you want to pay tribute. There's a reason [Dave's current band] Foo Fighters don't do Nirvana songs, and it's a good reason.''
