In 1936, All India Radio started to publish a magazine containing feature articles and a program guide for all the stations. It was called The Indian Listener. Here is the program guide for the Bombay station for Saturday, Jan 25, 1936. I have no doubt that the Shamshadbai shown here is non other than Saira Bano's maternal grandmother, of course, not to be confused with Shamshad Begum from Lahore.
