well....during the earlier live versions of the song at the ending, Stevie hit these incredibly high notes (almost in the vain of Mariah Carey)....anyway, it was almost as if she got stuck there and couldn't get out!!! you gotta hear it to believe it!!!

If you give me your email address or pm me i could try sending it to you. I think i have a clip from Philadelphia 3-77 where she does it.
