As their success grew, so did tensions within the band. In 1989, opening for The Rolling Stones, Rose threatened to leave the band if Stradlin, Slash, and Adler didn't stop "dancing with Mr. Brownstone," a reference to their song of the same name about heroin. After being sentenced to a year's probation for urinating in public aboard an airplane (after which the band nicknamed him "Whizzy"), Stradlin decided to attain sobriety; he returned to his house in Indiana, where he detoxed from drugs and alcohol.
