Often there are new or at least ADDITIONALL producers brought on for a b'way transfer. What do you mean by "previously used sets"? The ones used at the other venue (out of town or off b'way)? Often the set needs to re-realized for the new space so even if the design is nearly the same it is still mostly new. As far as the creative team...that depends. Most often that stays the same, but it's not UNheard of for there to be minimal changes.
If we're not having fun, then why are we doing it?
