In which movie kishore kumar has started his career as an actor?

For a long time it was known that 'Mukaddar' was his first movie. Some say Phani Mazumdar's "Andolon' is his first. Lots of people must have seen the clip where Kishore had a brief appearance in 'Ziddi' starring Dev Anand. But as per Kishore himself in a radio program in Kolkata in 1970/71 hosted by the the late Ajitesh Bannerjee the gteat drama personality, in a show sponsored by Horlicks, the health drink manufacturer, his first movie appearance was in 'Kaneez' and he acted in a crazy man's role. It would be nice if All India Radio, Kolkata can release those sponsored tapes or rerun again. I bet it will be a instant hit.
