Mos Def Records Hurricane Katrina Track

Mos Def has become the first artist to record a benefit single for the victims of Hurricane Katrina, in which he blasts George W. Bush and - more surprisingly - Bono.

The rapper, who recently starred in The Hitchhiker's Guide To The Galaxy, says that he wrote Katrina Klap after being inspired by TV footage he had seen in the wake of the August storm that has so devastated parts of southest America.

On the track Mos takes Bush and other leaders to task for their well documented slow response to the tragedy, but also blasts well known humanitarian Bono, accusing him of turning his back on the tragedy after spending so much time fighting poverty and Third World debt.

He raps, "It's enough to make you holler out/Like where the **** is Sir Bono and his famous friends now?/Don't get it twisted, man, I dig U2/But if you ain't about the ghetto, than **** you too/Who cares about rock and roll when babies can't eat food?"

No official release details are available for the track, though it is supposedly available on the Internet.

What odds a 50 Cent-style response from the little fella?
