And considering that the three of them are classically trained (meaning their voices have been trained to project without a microphone), that’s saying something!
Have you noticed how endearing Dame Shirley is as a guest? She goes to kiss all the other guests and gives audience a flying kiss and as for me each was sincere. Notice that and compare her act of greeting to other guests and you'll see why she is different.
I can tell you what makes her so different: I saw her years ago in a concert in Mannheim and after the show we waited outside only to see her going back on her tour bus. As she got in, she gave us last wave... and then she saw me standing there with my camera trying to make a last photo of her. She turned around just for me, got off the bus again and waved into my camera and so I got three wonderful pics of DSB. For me, that was the best moment of the whole concert.
