More than 150 fans of Lawrence Community Theatre – and of good singing – filled the big dining room at Maceli’s restaurant, 1031 N.H., on Valentine’s Day for a dinner and nearly two dozen “Songs for Sweethearts,” sung by six of LCT’s talented vocalists. Under the musical direction of Judy Heller and accompanied by Dee Blaser, the group sang tunes mostly from musicals performed at the theater during its 30 years in Lawrence, three decades in which 49 musicals and 184 plays altogether have been produced there.

The entertainment was capably MC’d by Curtis Marsh, who also strolled through the audience as he reprised “Where Is The Life I Lately Led?” from his performance in “Kiss Me Kate,” and “If Ever I Could Leave You” from “Camelot,” as well as joining in several ensemble numbers.

Daniel Lassley’s smooth lyric tenor was featured in “On The Street Where You Live” and “Brigadoon”s “Come to Me, Bend to Me.” Jayna French joined him in an exceptionally well-blended duet, “Love and Marriage.”

The male component was rounded out by Richard Walker in “Tammy” and “I Love Paris.” Walker was joined by Annette Cook in “Do You Love Me” from “Fiddler on the Roof,” performed in 1999 at LCT with Annette in the role of Golda, while Walker served as musical director.

Sarah Young was featured in “As Long As He Needs Me,” from “Oliver,” the first musical performed at LCT, in 1985. The number was dedicated to the late Art Sloan, who directed the show. Young also reprised “I Want to Be a Cowboy’s Sweetheart,” complete with yodeling, which she delivered in the LCT fall 2006 production of “Chaps,” and she filled the room with her resonant soprano in “Climb Every Mountain,” from her role as Mother Abbess in “The Sound of Music” in 2001. She and Marsh together gave a fine duet, “Wunderbar,” from their roles in the theater’s 2003 production of “Kiss Me Kate.”

Annette Cook opened with Stephen Foster’s “Beautiful Dreamer,” showed her mastery of the country idiom in belting out “Your Cheatin’ Heart” (accompanied on guitar by Walker) from her role as Patsy in “Always … Patsy Cline,” and added “Small World, Isn’t It?” from her role in the 2004 production of “Gypsy.”

Soprano Jayna French soloed in “Show Me,” from “My Fair Lady,” and in “Oh You Wonderful Boy” from “George M!” She also sang a torchy “Gimme Gimme That Thing Called Love” as a preview to this spring’s “Thoroughly Modern Millie” at the theater. She was joined by Young and Cook in the comic “All The Pretty Young Men” from “A … My Name Is Alice,” with all three doing a fine bit of comic acting as they sang.

Other crowd-pleasing ensemble numbers, sung by all six, included “Hello Dolly,” with Cook as Dolly, in a feathered headdress, circulating and flirting with audience members; “Try to Remember” from “The Fantasticks,” with voice-over memories of events at the theater over its 30 years; and “Funny Valentine” near the evening’s end. The show concluded with “Love is a Many Splendored Thing,” with the three men channeling the Four Aces’ 1955 sound, and then joined by the women.
