NEW YORK — John Lennon would have been 70 this week, and who better to honor his legacy in song than … Ozzy Osbourne ?

Yes, Ozzy Osbourne. The Black Sabbath heavy-metal king has made a cover of Lennon’s “How,” available Tuesday on iTunes to benefit Amnesty International.

Osbourne says Lennon was a “driving force for humanity.” He also credits the Beatles as the inspiration for his musical career.

A video for the song is debuting on AOL’s PopEater.com.

The former Beatle would have been 70 on Saturday. He was shot to death in December 1980.
