Cindy Lou (18, 28) knows she is the prettiest girl at Springfield High. She knows she will be named Prom Queen and acts out against her best friend Betty Jean when things don’t go her way. She makes the biggest change between Acts I & II, having learned the lessons of true love and loss. Vocal Range: Mezzo-Soprano Belt: E3–F5. Sings melody line on most songs, so the other girls hang their vocals on this voice. Among the songs she sings lead are: "Allegheny Moon," "Son of a Preacher Man," and "Maybe."
Missy (18, 28) is the over-achiever of the group. Very controlled, very concerned that everything at the prom turns out wonderful and perfect. Head of the Prom Decorations Committee, and absolutely smitten with her music teacher. Her best friend is Suzy. Vocal Range: Soprano: G3–A5. Wide range, floating high vocals and belting throughout the show. Among the songs she sings lead are: "Secret Love," "You Don’t Own Me," and "Wedding Bell Blues."
Betty Jean (18, 28) is the class clown and tomboy, always vying for attention with Cindy Lou, her best friend. It’s also highly probable that Betty Jean wants to be with Cindy Lou herself, but just doesn’t even know what those feelings really are. Cindy Lou steals Betty Jean’s boyfriend away, which causes a lot of the friction at the prom. She holds this grudge against Cindy Lou until they make up at the ten-year reunion. Vocal Range: Alto with strong low range: D3–E5. Among the songs she sings lead are: "Lipstick on Your Collar," "I Only Want To Be With You," and "That’s When The Tears Start."
Suzy (18, 28) is the gum-chewing, happy-go-lucky, go-along girl. Super-best friends with Missy, Suzy is always a little giddy and a little silly, and finds great pleasure in everything she does. In love with the lighting operator, completely surprised when named Prom Queen. Frustrated, sad, hormonal, and pregnant in Act II. This role requires an excellent part singer and expert comedienne. WARNING: Do not hire a ditzy person to play the "ditzy blonde." Vocal Range: Mezzo-Alto with both sweet and soulful voice: G3–E5. Among the songs she sings lead are: "Stupid Cupid," "Hold Me, Thrill Me," and "Rescue Me."
