The McGee Brothers were an American old-time performing duo consisting of brothers Sam McGee (b. Samuel Fleming McGee, May 1, 1894, d. August 21, 1975) and Kirk McGee (b. David Kirkland McGee, November 4, 1899, d. October 24, 1983). Sam typically played guitar and Kirk usually played banjo or fiddle, although they were both proficient in multiple string instruments. The McGee Brothers were one of the most enduring acts on the Grand Ole Opry during the show's first fifty years.
