The San Francisco Giants had a METALLICA theme night on Friday, and the band was there to participate.
Singer JAMES HETFIELD and guitarist KIRK HAMMETT played an INSTRUMENTAL version of the National Anthem on two Giants-themed guitars. They later signed the guitars, which were auctioned off for charity.
Drummer LARS ULRICH also threw out the first pitch. (Here's video of the National Anthem. The guitar auction raised more than $15,000 for the Giants' Community Fund and the Bill Graham Memorial Foundation.)
