BUTLER TWP — The “Broadway Bound” concert of the Butler County Symphony Orchestra on Saturday night might well have been titled “It’s a Grand Night for Singing.”

That’s because everyone — even the audience at the Butler Intermediate High School auditorium — got a chance to warble along with beloved tunes from the Great White Way.

Maestro Matthew Kraemer and the orchestra set the tempo for the evening with “Curtain Up,” a medley of perky melodies arranged by Bob Krogstad.

The medley included songs from “Annie Get Your Gun,” “Phantom of the Opera,” “Chorus Line,” “Funny Lady” and “Gypsy.” Broadway veteran Gary Mauer took the stage for “On the Street Where You Live” from the Lerner and Lowe classic, “My Fair Lady.” Mauer’s interpretation was charming and Kraemer restrained the orchestra to prevent the instruments from overpowering the vocal line.

Elizabeth Southard, also a Broadway veteran, responded with another song from the same show, “I Could Have Danced All Night.” She concluded the work with a lovely portamento to a shimmering high note.

In honor of the 50th anniversary of “The Sound of Music,” the audience joyfully took a turn at a singalong featuring seven of the most memorable tunes, including “Sound of Music,” “My Favorite Things,” “Sixteen Going on Seventeen,” “So Long, Farewell,” “Do Re Mi,” “Edelweiss” and “Climb Every Mountain.”

While it probably wasn’t up to Oscar Hammerstein’s performance standards, everyone seemed to have a great time.

Returning to the stage, Mauer got to show off his beautiful high tenor on “If Ever I Would Leave You” from another Lerner and Lowe classic, “Camelot.”

A less well-known song from a very well-known show was next as Southard presented “My White Knight” from Meredith Wilson’s “The Music Man.”

The two vocalists joined to present a “Tribute to Richard Rogers” which included “Hello Young Lovers,” “It Might as Well be Spring,” “This Can’t be Love” and an enchanting version of “Some Enchanted Evening.”

The second half of the program was devoted to more recent musicals, starting with an orchestral medley of Marvin Hamlisch’s “Chorus Line.”

Andrew Lloyd Webber’s phenomenally successful “Phantom of the Opera” was represented first by Southard in “Think of Me.” The tremulous initial notes reflected her character’s uncertainty but the concluding arpeggio showed off her operatic range and technique. Mauer replied with an excellent rendition of “Music of the Night,” which ended on a haunting, light high note.

Again the orchestra had time in the spotlight in the “Evita Medley” also based on the music of Lloyd Webber. The brash Latin rhythms and plaintive theme of “Don’t Cry for Me Argentina” were played with sensitivity and finesse.

Claude-Michel Schonberg’s enduring music from “Les Miserables” was excellently represented by Mauer’s rendition of “Bring Him Home,” which brought sympathetic tears to the eyes of many in the audience. Southard then beautifully sang “I Dreamed a Dream” from the same show.

The final instrumental piece was a medley from the hit show, “Chicago.” The sultry, jazz tunes of John Kander and Fred Erb conjured the wild culture of the mob-dominated 1920s. Maestro Kramer and the orchestra imbued the work with fun and fire.

Sung by Southard and Mauer, the poignant “Time to Say Goodbye” appropriately brought the curtain down on a delightful evening of the best of Broadway.
