The calendar may show that Valentine’s Day is more than a month away, but Playhouse Merced is already in the mood for love.

The theatre is opening up a three-weekend run of the musical comedy “I Love You, You’re Perfect, Now Change” at 7:30 p.m. tonight.

Through a series of musical numbers and comedy vignettes, the show examines all the varying stages of love and romance, from the single scene to first dates, to wedded bliss and children, and finally empty nest syndrome and dating later in life.

“I Love You, You’re Perfect, Now Change” features a cast of just four performers, who play all the various characters throughout the show, said Director Jim Kocher.

The musical originally opened as an Off-Broadway show in 1996, and went on to play more than 6,000 shows, making it the second most seen Off-Broadway show in history. Playhouse Merced first staged the show in the 2007-08 season, becoming one of the company’s most popular performances.

Playhouse Merced’s production is directed by Kocher, musically directed by Joel Scott Shade and features a Merced-based cast that includes Matt Capron, Colton Dennis, Bethy Harmelin and Dianne Kocher.

The show is rated M and contains mature themes, situations and language.

“I Love You, You’re Perfect, Now Change” opens tonight and plays three weekends through Jan. 26. Shows are at 7:30 p.m. Fridays and Saturdays and 2 p.m. Sundays. Tickets are $22 for adults; $20 for seniors; $12 for students; and $10 for children.  Purchase tickets by calling 725-8587, or visiting the box office at 452 W.
