Full of heart and 1960s flair, Hairspray follows Tracy Turnblad, a big-dreaming teen who lands a spot on “The Corny Collins Show.” But when she sees injustice in Baltimore, she sets out to integrate the dance floor, proving one girl can make a difference. With infectious songs like “Good Morning Baltimore” and “You Can’t Stop the Beat,” this musical makes the perfect closer to Music Theater Work’s 46th season: it is a joyful celebration of acceptance, self-love and standing up for what’s right.
