Book of Miracles / Juliet

[PDB]

I don't know if this has been discussed on this board before, but Stevie Nicks' "Juliet" from The Other Side of the Mirror came up on random play on my Zune yesterday and I remembered that I never found out the story behind the music in the song -- specifically that it's the exact same music as the Seven Wonders b-side "Book of Miracles". Is there a story behind the re-use of the music. For example, was Juliet supposed to be on Tango but they just did an instrumental and renamed it BoM, or did Stevie come up with lyrics for BoM later and rename it Juliet? Just curious...
