Last night my ears caught a snippet of Mariah Carey running the scales and octaves on a few Christmas tunes during her “Merry Christmas to You” special on ABC. But I had to put down the Christmas cards and watch when the Mary Lou Retton of vocal gymnastics was doing a duet with her mother, Patricia Carey. No matter what you think of Mariah or Christmas, the duet to Oh, Come, All ye Faithful is definitely worth a listen. What do you think?
