Sebastian Bach will replace Dee Snider as lead vocalist for a handful of select dates on the 50th anniversary tour of Twisted Sister, following her retirement from the band due to health issues. The announcement was made a month after Snider was forced to resign due to a series of health challenges, including degenerative arthritis, heart issues, and ongoing touring schedule. The band has not yet announced the full schedule of shows for the golden anniversary outing, which will include a stop at the Alaska State Fair on Sept. 4.
