In an interview about her Las Vegas shows 10 years ago or so, didn't she bring up that Rhiannon would be a great Broadway Show or play. I cant remember if she was asked about the movie and she pivoted to the show or how it came about.
She also said she was going to use a cordless mic and walk around the stage because it was so big. That never happened either
I think Stevie will play the soundtrack to Rhiannon on piano
