"the OBC went to LA and San Francisco, received rave reviews from the critics in both cities and proved a popular hit with audiences"
I saw the show in LA on a Saturday Night, and the theater was half empty. In addition, I saw around 100 people leaving at intermission. The show itself was not received heartily at the end of the performance as well. I stayed only because I have never walked out of a play in my life. My father, who works in Hollywood, also talked to a bunch of people who saw the show, some of whom were regular theater goers. About half of them walked out at intermission, and none of the rest liked it either. So it wasn't incredibly popular with my experience.
All the shows you mentioned mrkingas (With the exception of Jerry Springer) are classics, so of course they are going to be received well. Certain works can be universal in their theme, but in my opinion Caroline or Change was not good enough to warrent this universal theme. Caroline won't really relate to them as well. And Gospel never was as popular in London as it was in New York and London. Jerry Springer is an exception, and everyone could get that show because of the international success of the show.
Keep your morals, I don't have time. Keep your lovers, I'm changing mine!
