"Say You Will"

Is there a demo in circulation for this song? I was cleaning out my files yesterday (deleting multiple files of the same song etc...) and i came across "'Say You Will'-Stevie Nicks"...It was an incomplete file with only about 5% downloaded. It was just the beginning of the song before the vocal. Anyway, I think it was a mislabeled file. I believe the band, Foreigner, had a single of the same name back in the 80's and i'm pretty certain that's the song i had - not the Stevie demo.

Is there a legitimate demo for this?
