Metallica also played cover versions of Rare Earth's I Just Want To Celebrate, Deep Purple's When A Blind Man Cries and The Beatles' In My Life.
The band say in a statement: “It's no secret that Ozzy has been a major presence throughout our entire lives and we are so humbled and honoured to be with Ozzy for this special evening."

Also honoured at the event was Village Studios owner Jeff Greenberg who was given the From The Heart Award for his dedication to the mission and goals of the organisation. Musicares offers support and rehabilitation to musicians recovering from addiction.
