Anybody else heard Neil Young's "Let's Roll", about Flight 93, on the radio?

I've heard it twice today. A damn good blood-pumping song IMHO.

They say it won't be released commercially till his next album, and that instead it was shipped out to a few hundred radio stations, on hand-labeled CDs, with very little fanfare.
