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

It turns out that Back to the Beginning was part of a new beginning in the Osbourne family as Slipknot‘s Sid Wilson proposed to Kelly Osbourne backstage at the epic concert event that was serving as Ozzy Osbourne and Black Sabbath‘s farewell.

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 .
