Willie Phelps wrote the “Merry Christmas Polka” sometime around 1962 and it was recorded by Jim Reeves on his Twelve Songs of Christmas album in 1963. He is backed by The Anita Kerr Singers (Anita Kerr, Dorothy Ann Dillard, Louis Nunley, William Wright, Winifred Breast). There is a sub genre of Christmas songs that are Polkas and this is probably the most famous.
