We’re not sure what to expect from Psych‘s much-anticipated musical episode, but it looks like it will definitely have a Horror element.

Rocky Horror Picture Show actor Barry Bostwick has booked a guest appearance on the USA show’s two-hour musical episode, which was announced at Comic-Con this summer and is currently in production in Vancouver. He will play Armitage, a businessman and owner of a lavish theater in Santa Barbara.

Bostwick joins previously announced guest stars Brooke Lyons (2 Broke Girls) and Rent actor Anthony Rapp.

The episode will air during the show’s upcoming seventh season.
