Twisted Sister frontman Dee Snider is headed to Broadway to guest star in a performance of Rocktopia. Snider will be a special guest vocalist for one week of the show’s run in April.

Rocktopia combines the music of classical composers like Beethoven and Mozart with rock masterpieces by Queen, Zeppelin, Aerosmith and others, performed by elite vocalists, a live rock band, 20-piece orchestra, and a 30-person choir.

Cheap Trick’s Robin Zander and Train’s Pat Monahan have also been booked as guest vocalists.
