According to the picture on the left, it seems likely that Bill Ward will play with the rest of the original line up at the Download Festival on June 10th. It is also likely that Bill Ward will handle the sticks on the show at Lollapalooza on August 3rd.
The picture on the left is taken from the official Black Sabbath website.
The line up has not been confirmed by a press release.
The official Black Sabbath Twitter account was updated two days ago with the following message "Allright now!", followed by a YouTube-link to the song "Sweet Leaf".
