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 .

Fans travelled from across the world and sported their own rockstar outfits for the farewell - with everything from tattoos to socks bearing Osbourne's name or image. The legendary frontman, 76, who has Parkinson's disease, sang while seated on a black throne.

The metal luminary, 76, took the stage with his original bandmates at a farewell festival in his Birmingham, England, hometown on Saturday night.
