What should you call toughies who like to jump, shuffle, clap and pirouette at the slightest provocation? Hit the high notes at the flick of a pen knife? That would be the Jets or Sharks, while this here policeman is Officer Krupke. Maria and Tony, the starcrossed lovers. Protective brother Bernardo. Jealous beau Chino. Tony's bestfriend Riff. And there you have it, a musical based on the timeless plot of Shakespeare's Romeo and Juliet. Say it with music!
