Singer George Michael is recording an anti-war song in protest against possible military action in Iraq.
George Michael has been outspoken in his views
His version of Don McLean's The Grave will be played by MTV UK & Ireland across Europe from Monday.
The singer is one of the most high profile celebrities to have spoken out about the Iraq crisis.
The former Wham! star has also apologised to young pop artists for calling on them to abandon their plans for a new Band Aid-style charity song.
He had told BBC's Hardtalk programme that chart stars were too manufactured and trivial for any song to carry weight.
But on Friday's Channel 4's Richard And Judy show he said: "I think I was being a musical snob.
"I had a conversation with my sister today and she actually reminded me that it's not just about stopping this war, it's about keeping the pressure on."
His version of the 1971 McLean song, which featured on the American Pie album, keeps the hard hitting anti-war lyrics.
Michael has been criticised in the press after his video for his latest single, Shoot the Dog, showed Tony Blair as a poodle on the White House lawn.
Brent Hansen, chief executive of MTV Networks Europe, said: "George Michael has a history of expressing strong, personal views, with inimitable creativity and conviction that resonates with MTV Europe audiences."
Michael also performed an anti-war version of his hit Faith with Ms Dynamite at the Brit Awards.
Lee Ryan, of boy band Blue, wanted to enlist Kylie Minogue and Justin Timberlake for an anti-war track.
