Question: Dreams and Rhiannon live

[Rickypt]

I have a question for those of you with boots and/or old enough to have gone to FM shows in the 70's.

When was the last tour that Stevie was able to hit the high notes on Dreams and Rhiannon?

Specifically, when did she hit the high notes on "had" from "..what you had" and "life" and "stay" from "...all your life" and "...would you stay"?

Hope the question makes sense and thanks to anyone who has the answer.
