I don't know why this never came up on my radar.  It's a pretty touching tribute that Ozzy did for what would have been John Lennon's 70th birthday.  Check it out after the break.

Ozzy loved the Beatles and John Lennon in particular. He recorded this track as a benefit single. The video is pretty poignant as well (and I don't use words like "poignant").  It's just Ozzy trippin' around New York City.  Check out this cover of the song "How" below.
