The Billboard site mentions another duet that entered a chart.
Elvis Presley ends a decade's absence from Hot Country Songs, as "I'll Be Home for Christmas," with Carrie Underwood, opens at #60. The King last graced the list in January 1998 with his 1957 chestnut "Blue Christmas" (prior to a change in policy that allows only new holiday releases to impact the chart). "Home" and an updated version of "Blue" featuring Martina McBride appear on the new Presley release "Christmas Duets." He last reached Hot Country Songs with a non-seasonal entry when the double-sided remix single "I Was the One/Wear My Ring Around Your Neck" charted for two weeks in May 1983.
