Con-artist-turned-conductor, Harold Hill, The Music Man, is back in town, and we’ve got trouble. Meredith Wilson’s all-American salute to music, romance, and fast-talking flim-flam features songs such as “Seventy-Six Trombones,” “Trouble,” “Til There Was You,” and “Gary Indiana.” This hit revival is based on the 2000 Broadway production directed and choreographed by Wilmington native, Susan Stroman.
