This site (http://www.rockynewsgroup.org/GetArticle/2441.html) listed different ways to cast for "Rocky Horror," and here's how HOTC would be cast:

"Head of the Class" Cast (using original cast members ONLY)
DR. FRANK-N-FURTER: Charlie Moore
BRAD MAJORS: Arvid Engen
JANET WEISS: Darlene Merriman
RIFF-RAFF: Dennis Blunden
MAGENTA: Maria Borges
COLUMBIA: Simone Foster
DR. SCOTT: Jawarhalal Choudhury
ROCKY HORROR: Alan Pinkard
EDDIE: Eric Mardian
THE CRIMINOLOGIST: Dr. Harold Samuels

This one was listed as a description for a rock band site:
... Credits. Performed by Jawaharlal Choudhury, Simone Foster, Dennis Blunden, and
Arvid Engen. Recorded, Mixed, and Mastered by Mr. Charlie Moore at Woodshed.

The actual quote does not appear on the site itself. It must be really old stuff.
