Ozzfest forced to scrap final Ozzy Osbourne performance show

The OzzFest heavy metal tour has scrapped its final show and what would have been Ozzy Osbourne's final performance as a headlining act.

The tour's finale was supposed to be last week in Somerset, Wis., but the show was rescheduled for Sept. 10 because of Osbourne's vocal problems -- which forced his band Black Sabbath to sit out some of the shows this summer.

But a number of the bands on the tour could not make the rescheduled date, Billboard.com reported Wednesday.

A statement from the tour's organizers said they "felt it was best to cancel the (Wisconsin) show instead of mounting anything less than a spectacular event, as fans have come to expect from the festival over the course of 10 years."

Ozzfest will now close Sept. 4 in West Palm Beach, Fla.

Osbourne previously announced this would be his last year headlining the tour that bears his name.
