These two dates were at the end of the Dehumanizer tour.  Ozzy was saying that his 1992 tour was to be his last, and he wanted to play with Black Sabbath to "end his career".  Ronnie James Dio stated that he didn't think Black Sabbath should have to open for anyone, not the least of which was their own former lead singer, Ozzy. Dio refuses to do these shows, so Rob Halford (Judas Priest, Fight), a friend of the band steps in for these two dates.  Tony Martin was to perform at these two shows, but he was in Europe at the time, and could not get a work visa to come to the states and sing for Sabbath. The band (with Halford) does a Rockline interview on November 16, 1992, so Halford hung around for a bit more than just the two dates, but it was never intended to continue on with Halford as lead vocalist beyond these dates.

Here are some pictures from the Rob Halford led portion of the concert.
You'll have to excuse the quality of these shots. Video from this concert was never (ahem) officially released.
