The line outside the old ’20s gothic theater slinked around the corner off Broadway. Not that off Broadway. Broadway in Downtown Los Angeles, at the newly redone Ace Hotel, which, on this night in mid-September, sold out all 1,600 seats. No big musician was performing inside. No television show or movie was premiering (there aren’t any in LA, or anywhere, right now). The crowds were filing in to watch four women debate whether the sexual revolution has failed.
