Metallica entertained shoppers at a Los Angeles supermarket with an impromptu singalong to their classic hit Enter Sandman.
The band joined a member of the store’s staff in singing along to the track while customers looked on.
Comedian Billy Eichner was also part of the event, which is expected to appear on an upcoming episode of his show Billy On The Street.
It was captured on film by TMZ and the video can be viewed below.
They also discussed how their kids don’t care too much about their dads’ careers – with guitarist Kirk Hammett revealing that his children thought his instrument was “boring.”
