Are you being served in Australia

It seems likely that Joan is in fact watching "Are you being served in Australia?" - a spinoff featuring only John Inman from the UK cast. At least two other Prisoner supporting actors appeared in the series, as Robert reported in PCBH Digest 1191- "Actress Tracey Kelly ... appeared in "Are You Being Served In Australia" in the Miss Brahms part... Comedian Shane Bourne who had played several small roles in Prisoner played the cocky "Mr Lucas" part in the Aussie version of the sitcom.
