There's been some discussion of the potential musical, so I'm reviving this thread.
If you're interest in some (non-Eagles) background reading, here's a few suggestions:
1) Wikipedia explaining what a "juke box" musical is and giving a long list of such endeavors. https://en.wikipedia.org/wiki/Jukebox_musical
2) John Kenrick has an informative and entertaining website that covers everything about musicals, including the business aspects. http://www.musicals101.com/index.html
3) If you want to know the numbers, BroadwayWorld (BWW) has weekly reports on box office grosses. http://www.broadwayworld.com/grosses.cfm (I believe Playbill.com also covers the grosses).
4) When it works, the numbers can be huge. Here's the 10 top-grossing shows (only one is a jukebox musical) http://www.thefiscaltimes.com/Media/...ll-Time?page=9
5) Just because there's a rock star involved, doesn't mean it's going to make money. Just search on "Spider- man Turn Off the Dark" (Bono and The Edge) or "The Last Ship" (Sting), though these were both new material.
If you want to sit back and watch a fictional version of creating a new musical, you can try the tv series "Smash" although I remember the people who post on the BWW message board complained about it being unrealistic. Still, it shows some of the process and included many real musical theatre performers in the cast.
