Afloat with Henry Morgan was a 52 episode Australian series from, it is generally thought - 1933. Each episode was about 12 minutes long and the series was probably aimed at the youth market.
It is not to be confused with the US show - 'The Henry Morgan Show'.
It was produced by and starred George Edwards, who also produced Dr Jekyll and Mr Hyde, Frankenstein, Corsican Brothers, and Son of Porthos, all Australian series as well. We believe that Maurice Francis, an enthusiastic writer, and Nell Sterling, two of George Edwards long-time collaborators, were also featured in 'Afloat With Henry Morgan'.
To save money, Edwards played a variety of different roles and became known as 'the Man With A Thousand Voices'. It was a ventriloquial gift that encompassed small children, every variety of male voice, aged women, and foreigners. The maximum number of voices Edwards produced for a single scene was six; in the course of a single episode he would often double it.
