Bono and Alicia Keys have joined forces to record a cover version of the Peter Gabriel/Kate Bush song 'Don't Give Up' for charity.
Billboard reports that the song is titled 'Don't Give Up (Africa)' and all proceeds will be donated to Keep a Child Alive, the charity which provides medicine to families living with HIV/AIDS.
The track will be available exclusively on iTunes from Tuesday 6 December.
Bono and Keys first performed the song at a New York fundraiser for Keep a Child Alive on 3 November; Keys sang onstage at the function, while Bono sang the duet via a satellite link-up.
Commenting on the collaboration, Keys said in a statement: "I love this song. And I love Bono. I really respect what he has done for Africa and how he has used his fame to do good in the world. I hope I can do half as much in my life."
