Drummer Rick Allen (b. 1 November 1963) and guitarist Steve Clark (b. 23 April 1960) joined the band shortly thereafter. According to the band's official bio, their name was originally spelled Deaf Leopard. The band's early producer, Robert "Mutt" Lange, later produced (and married) country star Shania Twain. Drummer Rick Allen lost his left arm in a 1984 traffic accident, but learned to drum one-armed and continued on with the band. Willis was fired for drunkenness during the 1980s and replaced by guitarist Phil Collen. Guitarist Steve Clark died in 1991 after mixing painkillers with liquor; he was later replaced by Vivian Campbell. (Source: who2.com)
