Ozzy Osbourne pulls show at the last minute due to 'vocal concerns'

Ozzy Osbourne pulled out of a show on his 'Ozzy And Friends' live tour last night (June 20), despite his scheduled stage time being only minutes away.

The singer, who replaced almost all of his summer tour dates with Black Sabbath with 'Ozzy And Friends' shows while his bandmate Tony Iommi recovers from cancer, was due to perform at the SAP Arena in Mannheim, Germany last night and only cancelled a few minutes before the set was due to begin.

Osbourne left it so late in fact that support band Black Label Society had completed their set and fans were waiting for him to emerge. He has blamed the cancellation on "vocal issues".

Despite this, a representative for Osbourne told TMZ that the singer was in a good condition and the cancellation is simply down to vocal problems.

Fans at the SAP Arena show have been advised to check the venue's website to make sure they receive refunds for the cancellation.

Black Sabbath are currently in the midst of working on a new album and told NME earlier this month that they have written "15 new songs" for the album. Scroll down to the bottom of the page and click to watch them discuss their new record.
