You may not recognize Mal Evans' name, but you've definitely heard his work. The Beatles' road manager frequently lent a hand on recordings — he sounded an alarm clock on "A Day in the Life," banged a hammer on "Maxwell's Silver Hammer" and struck a cow bell on "With A Little Help From My Friends" — and his diary, made public in 2005, provided deep insight into the famed musicians' daily routines. After the band broke up, Evans moved to Los Angeles and began working on a memoir about his time with the Beatles. On January 5, 1976 police officers responded to reports of a domestic dispute at his apartment. Evans, who reportedly was on drugs, threatened them with a gun and was shot and killed. His cremated remains were sent to his family in England, but they got lost in the mail.
