Rocky Horror Elder
Rocky Horror Elders, generally speaking, were there from the beginning of the cult, but no longer perform.
Not to be confused with Rocky Horror Legend, which can be a person or place significant to the community, of any generation, including a Rocky Horror Middler (a long-performing, second-generation fan from the later '80s and into '90s).
