Harry Carroll (November 28, 1892, in Atlantic City, New Jersey – December 26, 1962, in Mount Carmel, Pennsylvania) was an American songwriter, pianist, and composer.Carroll taught himself how to play the piano and began playing in movie houses before he finished grade school. After he graduated from high school, he moved to New York City, where he worked as an arranger in Tin Pan Alley and at night entertained at the Garden Café and accompanied various vaudeville shows. He contributed the song (lyric by Ballard MacDonald) "Nix on the Concertina, Lena" to the Ziegfeld Follies of 1910.
In 1912, Carroll was hired by the Schubert brothers' Winter Garden productions as a contract writer. He worked with Arthur Fields to produce his first hit, On the Mississippi. In 1913 he again collaborated with Ballard MacDonald on the big hit song "The Trail of the Lonesome Pine." He wrote several Broadway stage scores including some popular favorites: "I'm Always Chasing Rainbows" (based on a section of Fantaisie-Impromptu by Frédéric Chopin), "By the Beautiful Sea" and "There's a Girl in the Heart of Maryland." Harry Carroll toured with vaudeville star Anna Wheaton for many years during this time.
