It's Lost in Translation time.  We're going down under for this installment, with a series that really pushed the envelope in Australia for most of the 70s, but barely made a whimper in the United States.  Was it because the American version didn't have the edginess?  Was it due to scheduling?  Could there have been too much going on?  Could it have been due to similar but more popular shows on other networks?  (Yes times four.)
