TVlives.com states: Maria Bird was a producer at the BBC and the original
narrator of Andy Pandy. Now there is something I'm very satisfied to read, there
had always been some doubt as to WHO was narrating these fifties episodes: If
you listen carefully, it is the same Maria then, who narrated Bill and Ben, as
well as 'Bizzy Lizzy'.
In Children's Tv On Trial Julia Williams says she voiced the 'Weeeeed' of Bill &
Ben! Vera McKechnie narrated the much later (1970 colour) eps. of Andy Pandy.
Very little is known of Maria Bird except that she shared an idyllic life with
Freda Lingstrom 'inventor' of children's Tv. David Oswell in his book on
children's television goes into detail about those early episodes: Maria,
narrating addresses the listening audience as well as speaks for Andy; "Have you
got a swing in your garden?-I expect some of you have"
