I imagine that the Black Sabbath four-piece section of the show will be pretty short, and the rest of it will be reminiscent of the Freddie Mercury tribute concert at Wembley Stadium, with the various other bands coming out to play with the Sabbath members on some well known songs.
It'll be incredible no doubt, but there will definitely be a home video release

As much as I dislike going to Manchester, I hate going to Brum even more
