Poison formed in Harrisburg, Pennsylvania in 1984 as Paris. They moved to Los Angeles in an ambulance Michaels bought for $700 and begin playing in clubs there. When their guitarist quit, they chose DeVille over Slash and Steve Silva, who also applied. Slash eventually joined Guns N' Roses and Silva was in the The Joe Perry Project. Poison got a record deal in 1986, disbanded in 1994 and re-formed in 1999. (thanks, Edward Pearce - Ashford, Kent, England, for above 2)
