Ozzy Osbourne and Black Sabbath's choice to play a final reunion gig in Birmingham has been described as a "homecoming" that recognises the city's status in music culture. The music icons will headline a one-day festival at Villa Park on 5 July dubbed "the greatest heavy metal show ever".

Well, there's some good news and some bad news as far as that goes. The good news is, Villa Park Arena has a capacity of more than 42,000 supporters across four stands currently (plans are to get it up to 50,000, but that won't be this side of Ozzy's curtain call).

Ozzy Osbourne will reunite with all of the original members of Black Sabbath for the first time in 20 years, in a gig that will be his last and that's being billed as the “greatest” heavy metal show ever,
