The day-long concert special featured standout performances from Osbourne and Black Sabbath, Metallica, Guns n' Roses, Jack Black and more.

Boozers were decked with purple balloons and flags; murals were everywhere you looked; people donned Ozzy outfits, flooding the streets with battered T-shirts and denim jackets. It felt like a World Cup final for the metal fans who flooded in from every corner of the planet .

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.
