A duet between Kurt Cobain and Courtney Love has surfaced online. The late Nirvana singer and his wife can be heard singing together on the track, "Stinking of You," which was never released, but appears in a new documentary film about Patty Schemel, former drummer with Courtney's band Hole.

In the video clip, Courtney can be seen playing an acoustic guitar while she and Kurt sing. The couple's daughter, Frances Bean, looks on. The documentary in which the song appears is called, Hit So Hard: The Life And Near Death Story Of Patty Schemel, and tells the story of the drummer and her self-destructive streak, as well as the Seattle music scene which spawned grunge in the early 90s.

Last week former Hole guitarist Eric Erlandson claimed Kurt had recorded enough material for a solo album before he committed suicide in 1994: "He was headed in a direction that was really cool. He was going towards, a solo album but working with different people. I was really excited about some of the stuff he was working on. I got to see him play it in front of me. That's why I was really sad when he died. He was cut short. Who knows where this music would have gone?"
