The moments where the extent of the problems with Ozzy’s health and the mistakes made in trying to fix them are laid out are unflinching but necessary. Understanding quite how hard his neck surgery issues (which left him, in Kelly’s words, “Like fucking Gollum”) and Parkinson’s made day to day life, with pain a near constant feature, is heartbreaking. You won’t be prepared for the scenes showing him weakened by and completely fed up with his predicament. Nor to see Sharon, the bombastic, unstoppable woman who never faced an opponent too big to fight against with everything she’s got, so broken down.
Where the joy that there is in this film lies is in what it captures as it follows Ozzy around. Making Patient Number 9 with his mates Andrew Watt (a man with an endearing ability to get Ozzy mucking about and who looks like every Backstreet Boy at once), RHCP drummer Chad Smith and Metallica bassist Rob Trujillo (also a veteran of Ozzy’s own band) you see the light come back in his eyes. Similarly, during prep for his turn at the Commonwealth Games with Sabbath bandmate Tony Iommi, a stunned Sharon notes that not only has her husband’s demeanour completely changed to how he used to be in preparing for a gig, he’s just walked from stage to car without his stick.
Even more stirring are the rehearsals for his induction into The Rock & Roll Hall Of Fame, itself touch and go as to whether doctors say Ozzy can travel there. Being unable to perform himself, his friends Billy Idol, Maynard James Keenan and Jelly Roll take the vocals on a trio of bangers, backed by Andrew Watt, Wolfgang Van Halen, Rob, Chad and Zakk Wylde, as Ozzy looks on from a throne. With no spoiler, it’s a genuinely wonderful thing that the cameras were there to record what happened. It’s also the only time award host Jack Black has ever been lost for words.
