Beer Barrel Polka played by Pat Walter with her Roland FR 4X and accompanied by herself with her Weltmeister Accordion. Just having fun for Okotoberfest time. Everyone seemed to like the last polka I – we did, so I thought, why not another. They are really fun to do, but a bit tricky. “Beer Barrel Polka”, also known as “The Barrel Polka” and “Roll Out the Barrel”, is a song which became popular worldwide during World War II. The music was composed by the Czech musician Jaromír Vejvoda in 1927.
