The net proceeds from the Plastic Ono Band's 40th anniversary digital version of "Give Peace a Chance" are to go to the United Nations Peacebuilding Fund, starting Tuesday and going through Dec. 31.
The song is available exclusively on iTunes.
"I am thrilled that so many in the music business are readily supporting 'Give Peace a Chance' on its 40th anniversary," Ono said in a statement. "It is indeed a time when we are all getting more aware of the necessity of doing something to achieve world peace, no matter how small. Thank you, thank you, thank you. I feel deeply that we are all one, regardless of where we stand."
"I am delighted to see that a song so closely identified with the pursuit of peace will shine a light on the United Nations' peacebuilding efforts and financially support PBF projects," added the chairperson of the United Nations Peacebuilding Commission, Ambassador Heraldo Munoz of Chile.
The song was written during John Lennon and Yoko Ono's 1969 honeymoon bed-in protest against the Vietnam War.
Sean and Julian Lennon are the sons of John, who was shot to death in New York in 1980.
