Despite an enviable string of chart-topping albums, Def Leppard once was the unluckiest band in rock 'n' roll.
Drummer Rick Allen suffered a near-fatal car crash in 1984, resulting in the loss of his left arm. Determined to continue performing with Def Leppard, he spent the next two years learning to drum with one limb.
Meanwhile, guitarist Steve Clark struggled with alcoholism throughout the decade. His condition had considerably worsened by 1990, prompting his band mates to grant him a six-month absence from the group. While on leave in January 1991, he ingested a fatal mix of alcohol and prescription pills.
Def Leppard was halfway through the recording of "Adrenalize," the band's fifth album, when Mr. Clark died.
