When someone in the upcoming New York City revival of Cy Coleman's I Love My Wife sings the title sentiment, it's probably true. Three of the four leads are knee-deep in wedding plans while performing in the Fourth Interval production, opening May 28.

Unlike the plotting of the Coleman-Michael Stewart musical comedy, J. Brandon Savage, who plays Alvin, and Elizabeth Shaw, as Monica, are set to marry in September while Julie Beckham, playing Cleo, will wed the production manager and lighting designer Scott Clyve. Matt Kuehl is the odd man out among the leads - he's not engaged to marry, but he has been engaged to play Wally.

Completing the cast are Douglas Martin, Scott Ragle, Spiff Wiegand and Jared Scott Stein.

I Love My Wife is set in Trenton, New Jersey during the wife-swapping, swinging 70's. Wally and Alvin decide to try out a foursome over Christmas and even get their wives to agree to the exchange. Unfortunately, the mathmatical possiblities may be more of a hinderance than a help and even a little naughty pot-smoking doesn't make the evening of fun any easier. Songs in the score include "Monica," "Someone Wonderful I Missed," "Sexually Free," "Hey There, Good Times," "Ev'rbody Today Is Turning On," "Married Couple Seeks Married Couple" and the title tune.

The original I Love My Wife, which debuted on Broadway in 1977, was a big hit, running 857 performances and winning two Tony Awards. Joanna Gleason (Into the Woods), James Naughton (Chicago), Ilene Graff and Lenny Baker were the original cast and recorded the album on DRG Records. John Znidarsic directs the Fourth Interval I Love My Wife. Stein is the musical director.

I Love My Wife plays through June 8. Tickets are $15-$12.50. The CAP21 Theatre is located at 15 West 28th Street. For reservations, call (212) 206-1515.
