Elvis Sings The Wonderful World Of Christmas is a 1971 album by Elvis Presley, and Elvis' second Christmas album. The album was released in October 1971, followed by the single from the album "Merry Christmas Baby" / "O Come All Ye Faithful" released in November 1971. This album was a top seller and topped the Billboard Holiday Albums Chart, and would have charted high on the Billboard 200 but from 1963 to 73 Holiday albums were not allowed to chart. But it did have the commercial appeal of Elvis’ first Christmas album. In addition it became a perennial favorite and over the years sold 3.4 million units.
