Signs in a Musical:

Aries: Wants to be the lead but often winds up playing funny background characters with lots of solos or comedic parts
Taurus: Plays a sarcastic character/ villain and often eats before and during rehearsals
Gemini: Plays a very high energy, comedic character, but isn't confident in their acting
Cancer: is one of the ensemble characters almost every time
Leo: plays the lead role
Virgo: would prefer to be watching the play but still participates with enthusiasm all the same no matter the role
Libra: got tricked into auditioning somehow by best friends and winds up getting a minor role in the play they didn't want to be in in the first place 
Scorpio: all of a sudden auditions for that very small role with one line because they get to say a curse word on stage
Sagittarius: is the side kick character
Capricorn: is the person who can probably sing really well but gets cast as a smaller role because of lack of acting skill.
Aquarius: is the person who probably can't sing but is cast into a major role anyways because of their acting ability
Pisces: Is that one character that makes all the puns and breaks the fourth wall a lot
