Ozzy Osbourne didn't even make most of the music or even write his lyrics.  This concert video portrays Ozzy at his dumbest.  Ozzy is the real life Homer Simpson, but annoying instead of funny.  Ozzy's voice is shrill, flat, off key and bad.  The only reason it doesn't sound too ear bursting on the video is because Sharon insisted that Ozzy re-record and do voice overs in the studio.
