Today's artists(?) try to hide their lack of talent with outrageous performances. Look at the singers from the past on Youtube and you'll notice (or not notice) the lack of props. They simply stand in there and sing.I did like Karen Carpenter.
I liked the composition of Natalie Cole's song, the "question and answer" format with the participation of the two female backing singers.
No fancy outfits, just a, "come as you are" effect, but great voices and excellent harmonisation.
