The plate she had put in her neck in 2001 fixed the problem ( a vanished disc ) but it was a squeaker- she has probably recovered about 90% of what she was before the problem developed. Unfortunately, her singing voice has never recovered- here once remarkable SATB range ( soprano, alto, teno, bass ) is gone.
It must be very hard losing her singing ability, but wonderful she's made such a recovery.
I've been watching helicopters today...quite a few of them. Don't think I've seen any since the thunderstorm.
