Watch Dolly Parton pay tribute to Ozzy Osbourne at the heavy metal legend's final concert, Back to the Beginning.

The set featured four songs from Osbourne's 1980 solo debut album Blizzard of Ozz, kicking off with "I Don't Know" and closing with "Crazy Train." The smash hit 1991 No More Tears ballad "Mama, I'm Coming Home" found the singer briefly (and understandably) overcome by the magnitude of the moment, but he soon found his footing.

Ozzy Osbourne has performed what he says is his final live show, thrilling 40,000 fans in Birmingham, England, on Saturday.
