Once again, Metallica’s James Hetfield and Kirk Hammett have performed a duo version of the “Star Spangled Banner” for their beloved San Francisco Giants. Blabbermouth reported the pair performed the National Anthem virtually before the September 23rd match-up between the Giants and the Colorado Rockies. This now marks the eighth time Hetfield and Hammett have done the pre-game honors, although this time marked the first not to be live and pre-recorded. Over the years, Metallica has also performed live prior to Golden State Warriors basketball and San Jose Sharks hockey games.
