The original lineup of Black Sabbath has confirmed their appearance at the 2005 edition of the Roskilde Festival, set to take place June 30-July 3 in Roskilde, Denmark.
"System Of A Down have already confirmed they will be playing the Sunday night, so we predict that Black Sabbath could fill the Saturday evening slot."
Download 2005 takes place at Donington Park in Derbyshire, UK on 11-12 June. Tickets will probably go on sale to Download members in early February.
