My Mother's Rings - any info?

[JimSATX]

Has anyone heard any lyrics or anything about this song? I know Stevie sometimes takes inspiration from old movies, and last night I was watching Play It As It Lays starring Tuesday Weld from 1972, based on the novel by Joan Didion. In it, the main character watches some old movies, and goes through her mother's things, and at one point says something like....These were my mother's rings....the silver one from Mexico...she always wanted to go to Mexico....

I could totally see Stevie winding these words into some of her lyrics. I'm hoping we'll finally get to hear this song one day soon
