Pop superstars Ed Sheeran and Will.i.am have recorded new versions of pop classics to raise awareness of poverty.
The singers are part of a campaign called agit8 which hopes to encourage politicians to focus on poverty.
Ed said: "Music is a powerful tool. There's no better way to get your point across than to put it in a beautiful song."
The campaigners hope top politicians will do more to help people in Africa after the G8 summit.
