Metallica's James Hetfield covered Adele's song 'Crazy for You' acoustically with his teenage daughter at a charity event in San Francisco at the weekend.
Hetfield and 16-year-old Cali performed the song - taken from the English singer's 2008 debut '19' - at the 'Acoustic-4-a-Cure' benefit concert for a children's hospital in San Francisco.
Hetfield is a co-founder of the concert series, which raises funds for children's brain tumour research.
