Nearly two years after it released "In Rainbows" as a pay-as-you-wish downloadable album, Radiohead has posted a new single on its Web site.

The song, "Harry Patch (In memory of)," is in honor of the last known British World War I veteran, who died in late July and was buried today.

"I had heard a very emotional interview with him a few years ago on the Today program on Radio4. The way he talked about war had a profound effect on me. It became the inspiration for a song that we happened to record a few weeks before his death," Thom Yorke, Radiohead's lead singer, said on the band's blog.

"I very much hope the song does justice to his memory as the last survivor. It would be very easy for our generation to forget the true horror of war, without the likes of Harry to remind us," he said.

The BBC is streaming the song online for free today, and Radiohead is selling the downloadable track for 1, or about $1.70. It says it is donating proceeds to the British Legion.
