Oanh Nguyen directs the musical with book, music and lyrics by Richard O'Brien, choreography by JT Horenstein and music direction by Mike Wilkins. The Rocky Horror Show will run Sept. 15-Nov. 6 in the Old Globe Theatre in San Diego.

McGrath appeared on Broadway as the Emcee in Sam Mendes' hit revival of Cabaret and in the international tour of Tom Waits and William S. Burroughs' The Black Rider: The Casting of the Magic Bullets directed by Robert Wilson. He has also appeared Off-Broadway in Hedwig and the Angry Itch and A Fair Country at Lincoln Center Theater.

Here's how Old Globe bills the show: "The musical that became a movie and started a 35-year nonstop cultural phenomenon is back where it is meant to be seen — live on stage. When Brad and Janet, a clean-cut young couple from the suburbs, get caught with a flat in the middle of nowhere, they seek help from the devilishly charming transvestite Dr. Frank 'N' Furter. What they discover in his mysterious laboratory is a time warp of sexual and scientific possibilities — and, perhaps, true love."

As previously announced, the cast of The Rocky Horror Show also includes Andrew Call (Eddie, Phantom), Jeanna de Waal (Janet), Sydney James Harcourt (Rocky), Nadine Isenegger (Columbia), Lauren Lim Jackson (Phantom), Kelsey Kurz (Brad), David Andrew Macdonald (Narrator, Dr. Scott), Anna Schnaitter (Phantom), Laura Shoop (Magenta), Kit Treece (Phantom) and Jason Wooten (Riff Raff).

The creative team also includes Donyale Werle (scenic design), Emily Rebholz (costume design), Rui Rita (lighting design), Kevin Kennedy (sound design), Aaron Rhyne (projection design) and Anjee Nero (stage manager).
