The Rocky Horror Show is a musical with music, lyrics and book by Richard O'Brien. A humorous tribute to various B movies associated with the science fiction and horror genres from the 1930s to the early 1960s, the musical tells the story of a newly engaged couple getting caught in a storm and coming to the home of a mad transvestite scientist, Dr Frank-N-Furter, unveiling his new creation, Rocky, a sort of Frankenstein-style monster in the form of an artificially made, fully grown, physically perfect muscle man complete "with blond hair and a tan".
