Metallica's Lars Ulrich sat down with Bob Buchmann of San Diego's Classic Rock Radio Station 101.5 KGB-FM before his WorldWired tour show at Petco Park on Sunday, August 6, 2017.

He tells on-air morning radio host Bob about his first time on the radio, whether he should be called "Sir" or not, what keeps him going and more!
