Duets

I was listening to the Power of Orange Knickers - Tori Amos featuring Damien Rice. I thought that two of my favourite singers could do a better job together. I don't know but Tori's last 3 albums sound all the same to me :( But the duet could be something much more intense, it's a shame really...
This makes me think about the great duets ever made...at this exact moment I can't remember any...Oh, Bjork and PJ Harvey once got together to sing "I can't get no satisfaction" and it was BRILLIANT! These collaborations are usually better than any recordings and, as they're so unique, they become memorable.
Here they are, together with Tori.
