Nick DeGruccio directs both matrimony-based musicals performed in repertory with two casts at the California company through Aug. 6, with a July 8 opening night.

With music by Harvey Schmidt and book and lyrics by Tom Jones, I Do! I Do! will star Julie Dixon Jackson and Tom Schmid. Jason Robert Brown's The Last Five Years features Misty Cotton and Daniel Tatar.

Based on the Jan de Hartog play The Four-Poster, the Schmidt-Jones musical follows "Michael and Agnes on their wedding day and traces their life together over a period of 50 years, until the day they leave their house to the next pair of newlyweds." The creators of The Fantasticks offer their take on happily ever after.

Brown's musical for two follows the five-year relationship between writer Jamie and actress Cathy — one character goes forward in time while the other journeys backwards from their breakup to their first meeting.

The design team for "The Marriage Musicals" features Tom Buderwitz (scenic), Steven Young (lighting), Jean-Pierre Dorleac (costume) and Rick Boot (sound). David Ossman is musical director and arranger. Production stage manager is Jill Gold and the assistant stage manager is Lea Chazin.
