George M. Cohan (1878, 1942) was an American composer, lyricist, actor, and producer who shaped American musical theater and popular song. Born into a vaudeville family, Cohan brought infectious energy and patriotic fervor to Broadway stages in the early twentieth century, writing some of the era's most memorable melodies.
Cohan's gift lay in crafting songs that stuck in listeners' heads and moved their feet. "You're a Grand Old Flag" exemplifies his talent for patriotic material with genuine warmth rather than bombast. The song became an instant standard and remains a fixture of American civic celebrations, school assemblies, and holiday programs.
