It starts with Sean Lennon and ends with John Lennon: a new version of "Give Peace A Chance," written during the Vietnam War by the slain Beatle and updated for the Persian Gulf war by his 15-year-old son.

The song and an accompanying video has begun airing around the country, says Mary Barnett of Virgin Records, the song's distributor.Joining Sean on the track were its producer Lenny Kravitz, Lennon's widow Yoko Ono, Tom Petty, M.C. Hammer, Peter Gabriel and Bonnie Raitt, among others.

"It's going to be in very heavy rotation," said MTV spokeswoman Carol Robinson, whose network is airing the clip.

Proceeds from the recording will go to the Spirit Foundation, the philanthropy founded by John Lennon and Yoko Ono.

Sean Lennon's new lyrics to the Vietnam-era peace anthem include this verse: "Everybody's talkin' 'bout, Civil War, Revolution, Armageddon, No solution, Are we facing Vietnam?, We don't want to drop the bomb."

It then picks up the chorus written by the slain ex-Beatle: "All we are saying is give peace a chance."

The video ends with John Lennon performing the original version at a bed-in for peace.

The song and the video were done in less than two weeks in order to send out the call for peace prior to the Jan. 15 U.N. deadline for Iraq to withdraw from Kuwait or face the threat of force. Sean and Kravitz got the idea while the teen was home on a holiday from school.

Tapings and tracks were done in New York, Los Angeles and London.

Other artists participating were L.L. Cool J, Run-DMC, Cyndi Lauper, Dave Stewart of Eurhythmics, Jazzy B. of Soul 2 Soul, Bruce Hornsby, Randy Newman, Little Richard, Iggy Pop, Terence Trent D'Arby, Little Steven, Duff McKagan of Guns N' Roses, Al Jarreau, rapper Q-Tip and Sebastian Bach of the band Skid Row.
