This song was not part of the film's original script. S.D. Burman had composed its tune without a brief. When Guru Dutt and Kafi Azmi heard the tune they loved it. Dutt asked Kaifi to write the lyrics for the song and said that he would find a way to accommodate it in the film. The song attained iconic status in the years to come.
Cinematographer V.K. Murthy won the Filmfare Award for Best Cinematography for this film. A highlight of his brilliant work in it was the effect of a beam of light he created in this song using a spotlight and two mirrors.[MR10]
A cover version of this song was recorded in Amitabh Bachchan's voice for the film "102 Not Out" (2018).
