The show also saw the frontman playing stripped back versions of two classic Metallica tracks
Metallica's James Hetfield covered The Beatles' 'ln My Life' at an acoustic fundraising event in San Francisco last night (May 15).
The frontman sang the track at the Acoustic-4-a-Cure event at The Fillmore for the Pediatric Cancer Program at the UCSF Benioff Children's Hospital, reports Rolling Stone.

Hetfield also sang stripped back versions of Metallica songs 'Nothing Else Matters' and 'Until It Sleeps' as well as appearing with Green Day's Billie Joe Armstrong and Joe Satriani to play Green Day's 'Boulevard of Broken Dreams' and Bob Seger's 'Turn the Page', which you can see below.
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.
