Osbourne provided the following details to Billboard, " Jack and I are doing a thing for the History Channel, like a father and son spoof on history. We went to Stonehenge and met a guy who thinks he's the f***ing reincarnation of King Arthur. And we went to Bletchley Park to see the machine [Alan Turing] used to break the [German] kind.

"We're going to Mount Rushmore, to the abandoned silos where America used to have their Minutemen missiles and all that. It's educational for me, actually -- history with an Osbourne slant."

Ozzy also elaborated more on his recent comments about Black Sabbath opting out of making a final album and explained the reasons why. "We were gonna do one before the tour, but it would take three or four years to write and record an album, by which time I'll be f***ing 73 or 72 or something, so we decided just to do a farewell tour.
