It Shoulda Been You is billed as "a musical comedy for anyone with parents. The bride is Jewish. The groom is Catholic. Her mother (played by Ms. Daly), is a force of nature, his mother (played by Ms. Harris) is a tempest in a cocktail shaker. And when the bride’s ex-boyfriend shows up, the perfect wedding starts to unravel faster than you can whistle 'Here Comes the Bride!' Plots are hatched, pacts are made, secrets exposed – and the sister of the bride is left to turn a tangled mess into happily ever after."
Richard Kline is best known for his work on TV's "Three's Company." On Broadway he has appeared in November, City of Angels and on tour in Wicked, Do I Hear a Waltz?, Oliver! and Jake's Women. George Street Playhouse is located at 9 Livingston Avenue. For ticket information visit GSPonline.org.
