And that’s all Black Sabbath said. No reason provided for the cancelled farewell show so far.
Black Sabbath will be replaced by Ozzy Osbourne’s solo act.

Could it be due to a new album in the making? After all, the band has said something about a final album to follow the album “13”.

Or could it be, like some people speculated, that the show is not a farewell show, just a final Japanese show?

Nothing is certain at this time, all we can do is wait for an official statement from the band.
