Just came across this little beauty. Norwegian singer Ane Brun has been supporting Peter Gabriel on his latest orchestral tour, and pitched in for the Kate Bush part in the classic duet "Don't Give Up", that graced Gabriel's most commercially successful album So (1986). At about 5:30 into the song, you should be alert, when the song gets a new coda not heard on record. The camera work is very unsteady - a mobile phone probably - but the sound quality is actually not bad.
