According to Wikipedia: Listen with Mother was a BBC radio programme for children which ran between 16 January 1950 until 10 September 1982.[1] It was originally produced by Freda Lingstrom and was presented over the years by Daphne Oxenford, Julia Lang, Eileen Browne, Dorothy Smith and others.[2]. . . .
