I'm going to guess that the theory behind mounting a tour after an unsuccessful run on b'way, is to get the name "out there" to improve the licensing of shows for regional, community and local theater.
We can take Legally Blonde as an example: closed on Bway at a loss. The tour did quite well, and since the rights became available, they are making money hand over fist. Schools and communities are clamoring to do this: lots of female parts and audiences are eating it up.
Granted, lots of unsuccessful shows DON'T find that kind of financial success later -- but they sure are aiming for it!
If we're not having fun, then why are we doing it?
