An "unforeseen family matter" has prompted Ozzy Osbourne to scrap his Thursday night (20Dec07) concert in Cleveland, Ohio. The rocker was billed to perform a pre-Christmas show with tourmate Rob Zombie at the Wolstein Center, but the show has been axed. Specific details about the family matter Osboourne must attend to have not been released. Zombie will now play a solo show at Cleveland's House of Blues instead. As WENN went to press there were no plans to cancel an upcoming New York show at Madison Square Garden on 22 December (07). This will be Osbourne and Zombie's last show of the year (07). They'll hit the road again on 3 January (08) with a concert in Maine.
