Rooster and Lily are quite the team -- "team" being the operative word, as the characters play off each other constantly. You might consider casting students of contrasting heights. Rooster can even be shorter than Lily; after all, these two are not to be taken too seriously! Rooster is flashy and self-assured. His "moves" should be as smooth as a gambler's, as should be the message he sells in "Easy Street." "Easy Street" is the most challenging number in the show, in terms of vocal range. If the students playing Rooster and Lily are strong both vocally and visually, the audience will feel like joining them in "Easy Street"!
