This is believed to be the only known video clip with sound of Civil War Veterans playing their instruments. It's likely either from the 1929 GAR Encampment in Portland, Maine (Sept. 813), or from the 1938 Reunion in Gettysburg, Pennsylvania, which had both Union and Confederate soldiers in attendance and occurred between June 29 and July 6.
