When you say 'yours', are you referring to Ms. Franklin or are you referring to the tradition of being dressed in Sunday-Best/Church Clothes? If referring to Sunday Best, in my case some Sundays I'm lucky to just make it in the church door and if that means I'm not wearing my Meeting clothes...oh well. I'm impressed by those who take the time to get dressed to the nines. If, however, you are referring to Ms.Franklin as yours, you seem to possibly be implying that she cannot be someone else's.
If one is an American, then Ms. Franklin is ours. If one is a student of history, then she is ours. If one is a lover of music, then she is ours.
The Grammy performance, while legendary and truly mind-blowing, was in 1998. Even her PBS concert from 2002 shows her in fine form, considering her age (66 now, since she was born in 1942) but Ms. Franklin's physical instrument is not what it once was. When I say that, does that mean that I don't hold her in the highest respect? No, it just means I have an opinion about the technical aspects of her singing. *No* singer's voice exists in a vacuum. The vocal cords age and thicken, the diaphragm can't exert the same amount of pressure, the lungs can't take in the same amount of air. For instance, Johnny Cash's voice in his latter years, was simply not the same as when he started out (with his age and previous hard-living), *but* he still could bring people to tears.
That being said, I think that her voice and the engine that runs that voice are possibly suffering from underlying physical issues

(that the public doesn't truly understand).
agnes!
