Jatlanders,
Below is the clip where we can see Sir Chhotu Ram live in a video. I ve uploaded it at youtube. Voice in video is of Mohammad Hayat. He is saying what Ch Chhotu Ram had said in this video while addressing:- "We will win, and after we win we will give you freedom. India will become free. That's what they said in those days."
In this video Ch Chhotu Ram is speaking at Soldier Recruitment Drive function for WW2.
Edit:- Moderators please correct the year as this video is from 1941. Thanks.
