During the shooting of the song tu pyar ka sagaar.....Balraj Sahni was in a hurry to go to airport to catch flight to go to somewhere, but the director insisted that the whole song must be shot on that day. So Balraj Sahni took a chair and sat and shot for the song. The whole song he was sitting on chair and he was singing and the whole song was picturised in 3 shots and in 1 take in short time and he completed to shoot tu pyar ka sagaar....he went away to airport and reached on time. The song doesn't look it was shot fast in a day. That was Balraj Sahni.
