NEW YORK (CBS/AP) Ozzy Osbourne, the self-proclaimed "Prince of Darkness," is showing off his melodic side while paying tribute to one of his main musical influences, John Lennon.
The Black Sabbath frontman honored Lennon, who would have turned 70 Saturday, and his musical legacy by recording a cover version of his song, "How," a single from his 1971 "Imagine" album.
Osbourne told the Associated Press that Lennon was a "driving force for humanity." The heavy-metal singer has often expressed his admiration for Lennon and The Beatles, crediting them as the inspiration behind his musical career.
"When I heard The Beatles, I said, 'That's it. That's what I want to be. I want to be a Beatle,'" Osbourne told NPR earlier this year. "I bought the Beatle suit, the Beatle wig, the Beatle photographs -- anything with The Beatles."
Osbourne's version of "How" is available Tuesday on iTunes, with all proceeds going to Amnesty International.
