Music composer and singer kishore kumar for the first time, they got the chance to work together in this film, kishore kumar sang the song ' hello kya baat hai.....' with asha bhosle. But rajendra kumar got the song deleted as he thought kishore kumar voice doesnt suit him. Kishore kumar was annoyed with rajendra as after about 30 years he got opportunity to sing for naushad and then the song should not be heard or seen. Kishore kumar decided that he wont sing for rajendra kumar forever (wrong information that Kishore Kumar never playback for Rajendra Kumar. In fact, Kishore Kumar playback for Rajendra Kumar for movie
Aap Aye Bahar Ayi). Naushad and kishore kumar never got a chance to work again. Years later kishore kumar, had gone to a recording studio and he was to record a song for love story, which would have come in the background of the film, before the recording kishore kumar that ' who is the producer of this film ?' When he was told that rajendra kumar is the producer, at that moment only kishore kumar walked out of the studio without recording and that song was scrapped.
