One iconic horror show is "The Rocky Horror Show," a musical first performed in 1973. It humorously plays with B movies from science fiction and horror genres, telling the story of a newly engaged couple who end up in the castle of Dr. Frank-N-Furter, a mad transvestite scientist unveiling his creation, Rocky. The show includes popular songs like "Time Warp" and "Sweet Transvestite." It later inspired the famous 1975 cult film "The Rocky Horror Picture Show" known for its unique blend of horror, comedy, and music with lasting cultural impact.

If interested, there are ongoing tours and performances of the musical even in 2024 and 2025 across various locations.
