Ozzy Osbourne will apparently sing 'four songs' today according to Black Sabbath's Tony Iommi. In a new interview with BBC Midlands Today, the heavy metal guitarist said while Ozzy might not be able to do the whole show, he would do 'four songs'.

The gig at Aston Villa Football Club’s Villa Park stadium will also feature sets by US rockers Metallica, Guns N’Roses, Tool and Slayer among others, as well as a short solo set by Osbourne. Around 40,000 fans are expected to watch the original line-up’s first show together in 20 years and Osbourne’s swansong.

Tens of thousands of fans will rock out in Birmingham on Saturday as Ozzy Osbourne and Black Sabbath reunite for what they have said will be their last live performance together.
