Guns N’ Roses, Tool, producer/musician Andrew Watt, Red Hot Chili Peppers drummer Chad Smith and Living Colour guitarist Vernon Reid have been added to the lineup for Back to the Beginning, the massive final Black Sabbath concert on July 5 in the latter band’s hometown of Birmingham, England.

And aside from all of the stars coming out to see Ozzy and Black Sabbath off into the sunset, it shouldn’t get lost in the sauce that this will be the first time that Osbourne, Tony Iommi, Geezer Butler, and Bill Ward will play together in 20 years.

He will reunite with the original Black Sabbath lineup for what will most likely be his final performance. The show is happening in the band’s Birmingham hometown this summer, and it will include performances from both Sabbath and solo Ozzy Osbourne.
