Comic Jackie Mason pulled out of a two-night stand at Skokie’s North Shore Center for the Performing Arts today, just hours before he was set to open. The official reason? A scheduling conflict with a TV pilot. The Mason show, which reportedly was selling well, has been rescheduled for October 16 and 17. Ticket holders are being asked to visit the box office at 9501 Skokie Blvd., or call 847-673-6300 to reschedule or for refunds.
