I have no basis in fact for saying this, but B&S would be crazy not to bring this stateside, even just for a handful of dates. They could easily sell out 2 nights at Radio City Music Hall and 2 nights at the Greek Theater in LA. Throw in the Greek Theater in Berkeley, the Chicago Auditorium, and maybe one or 2 other cities and that's a nice chunk of change. That would probably make it well worth their while to hop the pond.
