Woh Mangal Raat Suhani Thi Wo Piya Se Chudne Wali Thi Song Exclusive -

Wait, actually, I think it's from a play or a song that's been popular for a while, maybe "Rasik Kalakar" or another traditional play. Let me verify. A quick search in my mind: "Woh Mangal Raat Suhani Thi" is from the play "Rasik Kalakar," which is a classical play by Vishnushankar Pandit. It's a love story and this song is part of the play's repertoire. However, in Hindi cinema, the song might have been used in a movie adaptation. Alternatively, maybe it's from a film like "Kabhi Kabhie" (1973) or another older film.
