The trumpet “Charge,” heard often at athletic contests, was composed by a post-World War II USC student named Tommy Walker. As a member of the Trojan Marching Band, he was known as “Tommy Trojan,” and as a USC football player, he would shed his band uniform, come down from the stands, and kick extra points (he lettered in 1947). Upon graduation in 1948, he was hired as the band’s director. He later was the first entertainment director at Disneyland and then went into business as one of the world’s leading creators of show business spectacles (including Super Bowl halftimes and Olympic opening and closing ceremonies). He died in 1986.
