Yoko Ono is urging John Lennon fans to celebrate the late Beatles star's 70th birthday by voting for his Educational Tour Bus to win a $250,000 (£156,250) charity grant.
The mobile recording and multimedia studio enables youngsters in the U.S. to record their own music, with sound engineers on hand to help students produce projects.
Ono wants to take the initiative global to coincide with what would have been Lennon's 70th birthday in October (10) - and she's eyeing a cash sum from the latest Pepsi Refresh Celebrity Challenge.
In a video message, she says, "The John Lennon Educational Tour Bus is something I really feel will change the world. It goes to every village and every town and educates children. I hope people will support this cause as it will mean so much to your children and grandchildren and the world.
"We have to do this. I really wish that people will help us do that (take the bus global). Now they know what is going on in the United States, we should share it with the world."
