Brooks and Marsh have 'Lucy in Connecticut' as the title for those season 6 episodes, as they were were re-aired in prime time, on CBS, on Sunday nights in the summer of 1960. As far as I know, that title was not used in syndication, or for any other run on CBS. Incidentally, CBS had already used 'The Lucy Show', and two variations, as a title for 'I Love Lucy' reruns that aired on the network while ' ILL' was stil in production; in the summer of '55, it was 'The Sunday Lucy Show', and that fall the repeats moved to Saturdays as 'The Lucy Show'. CBS also had a 'Top Ten Lucy Shows' series in the summer of '58...which ran 13 weeks.
