Heavy metal legends Black Sabbath closed out the 2012 Download festival Sunday night at Donington Park in England.  Three of the band's four original members took part, including frontman Ozzy Osbourne, guitar legend Tony Iommi and bassist Geezer Butler.  The lone original member not present was Bill Ward, who declared a few weeks ago that he would not be taking part in the reunion, indicating he could not come to terms on a contract with the band.  Ward was replaced at Sunday's show by Tommy Clufetos, who played on Ozzy's latest album but has also played with artists such as Ted Nugent, Alice Cooper, Robb Zombie and John 5.  Check out a clip of Sabbath's encore performance of "Paranoid" below.
