Old Reuben may be a hick, but he knows a thing or two about boys who've seen the world. This song was very popular and was performed by many bands, including the "Harlem Hellfighters," the fighting musical unit led by James Reese Europe. After fighting in France with the French army, (since the segregated American army would not allow them to serve as a fighting unit), they returned as heroes and had a parade up Fifth Avenue to Harlem, the only victory parade to do so. The song is lots of fun, but quite poignant when one thinks of the men in Europe's unit.
