It depends on what kind of reunion you want to know about. The
possibility of Ozzy and the three Sabs reuniting as a permanent
group is nill. It just won't happen. A partial reunion for the sake of
fans (or should I say fan$) is probable.
What you may not know is that during the time Ozzy was playing his last
show in Costa Mesa with his old Sabbath buddies, the foursome had already
been talking for nearly a year about a reunion. It was originally going to
be a two month tour and an album (a Sabbath-head's dream come true). As
time progressed though, Ozzy grew uncomfortable about doing the reunion.
Problems began arising... the four original members now had their own
managers, lawyers, and record companies. Each person's manager wanted to be
the one in charge of the project which would result in a fortune. The Sabs
just wanted to do the show. Ozzy has since gone on to say that he might
have done a reunion if they had scrapped the name Black Sabbath at the time
when the original members left. As it stands, Black Sabbath has had members
leave, come back and then leave again. There have been numerous changes in
the members of the band involving outside players. Ozzy felt that the name
Black Sabbath no longer represented what it once did. This chapter deals
the idea of Black Sabbath reunited for good. In fact, Black Sabbath and Ozzy
HAVE reunited for concerts, but both remain two separate bands.
Since the Costa Mesa show, Ozzy has agreed to reunite with Sabbath for
a small tour. This coincided with a live album which was released
October 31, 1998. This will not be a permanent reunion, however the
band is touring North America in 1999.
