Watch: Ozzy Osbourne sings Iron Man at Black Sabbath's final gig

Black Sabbath went out with a bang on Saturday night at what the band said would be its final gig.

As they played one of their most-recognisable songs, Iron Man, fans sang along with lead singer Ozzy Osbourne at Villa Park in Birmingham.

Ozzy, 76, who has Parkinson's disease, sang while seated on a black throne - encouraging the crowd to sing louder, and pulling wild-eyed looks, just like old times.
