This song is a duet with Luciano Pavarotti singing in Italian and Zucchero singing English lyrics written by U2's Bono. Zucchero composed "Miserere" with Pavarotti in mind.
Pavarotti was reluctant to record without first hearing a demo. During auditions for a demo to send to the Italian tenor Zucchero, he came across a blind lawyer who worked as a piano player in a bar in Pisa. The pianist was a then unknown Andrea Bocelli, who agreed to make a demo with Zucchero. After hearing the demo recording, Pavarotti at first urged Zucchero to use Bocelli instead of himself, but then agreed he would accompany Zucchero. Andrea Bocelli later turned into one of the best selling Opera and Pop singers in the world.
The success of this song led to the longrunning Pavarotti and Friends concert series, in which Zucchero was a regular guest.
Michael Kamen was in charge of the orchestra on this.
