Hetfield also played an acoustic set with the rest of Metallica in Los Angeles earlier this week in tribute to Ozzy Osbourne at a charity gig for the MusiCares MAP Fund, which helps musicians recover from addiction. The four-song show at Club Nokia began with Hetfield playing 'Stairway To Heaven' followed by Rare Earth's 1971 hit 'I Just Want to Celebrate'. The band's set also included Deep's 'When a Blind Man Cries' as well as The Beatles' 'In My Life'. They closed the set with a reading of Ozzy Osbourne's 'Diary Of A Madman'.
Metallica will headline next month's Glastonbury Festival.
