"Theatre in the Heart of the City" will be the theme of Salt Lake Repertory Theatre's (City Rep) first full mainstage season in its new home, the Utah Theatre at 148 S. Main.

The company's third season will include five musicals and two plays with music, along with an expanded schedule of 10 performances for each of the seven full-scale productions.Here is City Rep's 1988-89 mainstage lineup.

- "Girl Crazy" (Sept. 23-Oct. 15), the George and Ira Gershwin hit from the 1930s featuring such hits as "I Got Rhythm" and "Embraceable You." It is expected that June Allyson, who starred in the 1943 screen version (with Judy Garland and Mickey Rooney), will be able to attend the opening performance.

- "The Mystery of Edwin Drood" (Oct. 28-Nov. 19), a musical farce based on Charles Dickens' mysterious, unfinished novel. It played to capacity crowds at City Rep's 2nd Stage theater during the 1987-88 season.

- "Babes in Toyland" (Dec. 2 through Christmas Eve). A revival of City Rep's holiday production last season at Kingsbury Hall. It is hoped that this will be augmented by another Christmas-oriented show in the upstairs theater at the Utah Theatre.

- "See How They Run" (Feb. 3-25), a comedy set in World War II era English countryside, involving a vicar's wife, escaped German prisoners, nosey neighbors and wacky maids.

- "On the Twentieth Century" (March 10-April 1), a musical-comedy set aboard the luxurious cross-country train.

- "The Star Wagon" (April 14-May 6), an award-winning comedy by Maxwell Anderson about two exploited senior citizens who travel back to the innocent days of their youth. This time they vow to marry for money and power instead of love.

- "The Desert Song" (May 19-June 10) is the popular Sigmund Romberg operetta, with lyrics by Oscar Hammerstein II and Otto Harbach.

City Rep Artistic Director Joanne M. Parker said the season should give performers in the community "a wide variety of roles to audition for."

The City Rep calendar will be expanded for the 1988-89 season to include one each additional Thursday and Friday evening performance. One Saturday matinee and one Monday evening performance also will remain on the schedule. All evening performances will begin at 7:30 p.m.

Season ticket prices start at $35 and subscription renewals will be accepted through June 1. Discounts also are available for senior citizens, children and groups.
