I first heard this tune as part of a Heineken spot on TV, so, I looked it up on YouTube, and found this video, from a 1965 film. The words are transcribed on the video. The girl dancing is adorable, her name is Laxmi Chhaya, there is not much info on her, she passed away in 2004 and the man you hear singing the song, Mohammed Rafi died in 1980. By the way, he is not the guy pretending to sing in the video. Anyway,  I cannot get enough of this tune right now. Great song, love the music.
