Agree with you, Chris!Karen and Richard together were like peanut butter and jelly on those records. Both were phenomenal and noteworthy in their own individual talents, but put them together and you have a whole other dynamic going on that is exponential. I enjoy hearing the doubled vocal by Richard, which sets up the anticipation while awaiting Karen's entrance. Just perfect
Perhaps that's why my favorite of the Christmas records only have Karen and Richard and no chorale. The ones with the chorale are superb, but nothing beats the homespun arrangements of "Merry Christmas Darling" and "Santa Claus..."
