Black Sabbath performed “War Pigs,” “N.I.B.,” “Iron Man” and “Paranoid” — while Osbourne, 76, also performed solo songs such as “I Don’t Know,” “Mr. Crowley,” “Suicide Solution,” “Mama, I’m Coming Home” and “Crazy Train.”

Black Sabbath — consisting of Osbourne, Geezer Butler, Tony Iommi and Bill Ward — held their star-studded goodbye concert “Back to the Beginning” at Villa Park Stadium in Birmingham, England, where the band was formed in 1968.

The proposal happened at backstage at Birmingham, England’s Villa Park on Saturday after the final Black Sabbath show.
