According to a short message that was just posted on ANTHRAX's official Twitter account, MEGADETH mainman Dave Mustaine's claim that ANTHRAX guitarist Scott Ian told Dave that METALLICA was planning on firing drummer Lars Ulrich in 1986 is "not true." The post adds, "Little does anyone know but Lars actually owns the [METALLICA] name. Good luck ever kicking him out."
In a brand new interview with RollingStone.com, Mustaine — who was a member of METALLICA for less than two years in 1981-1983 — was asked if, as far as he knows, it is true that on the last METALLICA tour Cliff Burton was on before he died, the band was planning on firing Lars Ulrich at the tour's end. "That's what Scott [Ian] told me," Dave replied. "He said that when METALLICA got home, that James [Hetfield], Cliff [Burton] and Kirk [Hammett] were going to fire Lars."
In April 1983, after METALLICA had driven to New York to record their debut album, Mustaine was officially fired from the group — allegedly because of his heavy drinking and personality clashes with founding members Hetfield and Ulrich. The band packed up Mustaine's gear, drove him to a Greyhound bus station in Rochester, New York and put him on a bus bound for Los Angeles.
