LOS ANGELES—A national coalition of Aerosmith fans, frustrated by the weak, power-ballad-filled mediocrity of such recent Aerosmith albums as Get A Grip and Pump, has collected three million signatures on a petition imploring the veteran rock quintet to return to drug addiction. "We, the united fans of Aerosmith," the petition read in part, "plead with you to resume the type of liberal use of heroin and cocaine that fueled kick-ass albums like 1976's Rocks and classic tunes like 'Back In The Saddle.' We would additionally like to see a marked increase in alcohol abuse, particularly from one-time 'Toxic Twin' Joe Perry, who, regrettably, has not had a monster riff since 1980."
