Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward all grew up within a few streets of each other, a stone's throw from the Aston stadium. The band's relevance to the city's cultural heritage was recognised when they were awarded the Freedom of Birmingham last weekend.

After Metallica’s performance, Osbourne, 76, came out on stage and performed a five-song set by himself, before he was joined by his former bandmates Tony Iommi, Bill Ward and Geezer Butler for four of the group’s songs.
