Bob, This is a very cool idea and a resource that is currently lacking. I would say that the page should include:
Joni mentions (or mentions of Joni's songs or paintings) in books; Joni mentions (or her music or paintings) used in films. This should, in my opinion, include when her songs are performed by others as well. (But it's just my opinion.) I can give you a pretty good head start on Joni songs in movies, both by Joni and covers. Just when you thought the JMDL couldn't get any better! :~) SCJoniBob NP: Elvis C, "Sweet Dreams"
