that's a shame.
She had appeared to be winning the battle for a long time, then it took a turn for the worse

Now she's leaving on a jet plane, and won't be back again

and once again the curse of three strikes. Three famous people in a row.
Henry Gibson, Mary Travers, and Jody Powell.

three great people.
