LEGAL FILE

Singer Pleads Innocent: The lead singer of the rock group Skid Row, which opened for Aerosmith in Springfield, Mass., has pleaded innocent to assault and mayhem charges. Sebastian Bach, whose real name is Sebastian Bierk, allegedly hit a fan in the face with a beer bottle, breaking her nose and skull, then leaped from the stage and kicked another person in the head. Bierk told authorities he was antagonized by some in Wednesday night’s Springfield audience of about 9,500. Bierk, 21, of Monmouth Beach, N.J., returned to the stage after the scuffle and finished his gig, and Aerosmith performed as scheduled. Bierk is free on $10,000 cash bail.
