A charity release to raise cash to help children afflicted by AIDS goes on sale exclusively through iTunes next week.

Contact Music reports that U2 frontman Bono and R&B star Alicia Keys (both of which have shared a stage with Apple CEO Steve Jobs) have recorded the song, an adaptation of the Peter Gabriel and Kate Bush song, "Don't give up (Africa)".

All proceeds from the track - which will be available from all music retailers - will go to the Keep A Child Alive charity, which Keys supports.

She said: "I believe AIDS is the most important issue we face, because how we treat the poor is a reflection of who we are as a people. I urge everyone to recognise the extreme disaster Africa is facing and step up for the Motherland."

Almost five million people contracted AIDS/HIV this year. There are 40.3 million people living with the virus today. 570,000 children died from AIDS this year, the United Nations revealed last week.

The song and accompanying video is available to listen and view on the Keep A Child Alive website.
