Today, I kind of share Jack Campin's astonishment and dismay,
although I knew about Betty Carter's passing at the time, because:

one of Carter's mentored students was pianist Geri Allen.
A lovely short video can be seen of an elderly Betty Carter
(she is in fact balding and bare-headed, makes her look severe)
singing "Lonely Town",
words by Langston Hughes and music by Kurt Weill.
A youthful and glamorous-looking Geri Allen plays the piano
as part of the backing trio.

Now I find out that Geri Allen died of cancer last year.
Heck, it's bad enough saying goodbye to Betty Carter --

now her babies are passing away as well. End of an era.
