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 .

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

The epic 'Back to the Beginning' send-off was held at Villa Park in Birmingham, England, and streamed live globally.
