The Usherette is a character originated by Patricia Quinn in the original 1973 London Cast of The Rocky Horror Show. The character represents the cinema usherettes of the 1920s through 50s that showed patrons to their seats and sold refreshments via a concession box worn at the waist. In The Rocky Horror Show, she literally ushers in the story by singing the opening number from the show, "Science Fiction, Double Feature", and later signals the conclusion of the show with "Science Fiction, Double Feature (Reprise)".
The script is vague in regards to this character, referring to her as Magenta (as Usherette). The tray she carried as the Usherette contains a prop with the words "Strawberry Time", which the cast then expanded to call her "Miss Strawberry Time", however the character is not referred to in the musical. When the show opened in the US in 1974 at the Roxy Theatre, the Usherette was played by Jamie Donnelly, and became known as "Trixie", having "Hi...I'm Trixie" written across the front of the tray in place of "Strawberry Time".
The Usherette is a personification of the The Lips singing "Science Fiction, Double Feature" during the opening credits of The Rocky Horror Picture Show and her performance is open to interpretation. The Usherette was featured on film for the first time in The Rocky Horror Picture Show: Let's Do the Time Warp Again, played by Ivy Levan.
