Ozzy Osbourne is ready for his slippers
The years of drug abuse, alcoholism and bat-chewing - not to mention the 2003 quad-bike accident that almost cost him his life - have clearly taken their toll on Ozzy Osbourne: the figure on stage in his home town, the heartland of heavy metal, was a pale and rather pathetic shadow of the man who used to be the charismatic frontman of the world's most awesome heavy metal band, Black Sabbath.
Once upon a time, Osbourne used to channel the ferocity of his band's dark riffery like a maestro of malevolence; here, he had about as much charisma as Timmy Mallett, and walked the stage with the shuffling gait, familiar to viewers of The Osbournes, of someone who has lost a great many neurons.
"Are you ready to go crazy? Come on then, let's go crazy," he yelled at the crowd at the start of the Birmingham leg of his world tour. The crowd went a little bit wild for a while, but although Osbourne kept shouting at us, with increasing desperation, to "go f***ing crazy", there wasn't a lot to go crazy about.
