The Hard Rock Cafe has launched its global Imagine There's No Hunger campaign, which will benefit WHY (World Hunger Year), a non-profit organisation that strives to fight against hunger and poverty around the world.
Yoko Ono has donated John Lennon's song Give Peace A Chance to the Serve3 compilation CD. And the CD also features an exclusive track by Joss Stone, Love Has Made You Beautiful.
The British soul singer visited the Hard Rock Cafe in London this morning to help launch the campaign.
She said: "I think that if you can help in these situations then you definitely should. There is no need for millions and millions of people to be dying from hunger. Where we are right now it just doesn't need to happen."
Joss explained she wrote the song about a friend, when she was 15.
She said: "It's not about the visual (how someone looks) - it never was and it never will be. It's about a feeling that comes from you, the words that come out of your mouth, the things you do with your life.
"I believe that in any charity this fits - if you do something good then it will affect the world in a positive way, that's what makes you a beautiful person."
The CD, Serve3, and Imagine There's No Hunger merchandise will be available to buy at Hard Rock locations around the world from November 4.
