The audio records of this film incorrectly credited Hamsika Iyer as the vocalist for this track although it was sung by Aditi Singh Sharma.
While there were four versions of this song in the film album, this version was used in the film. The song sequence was shot in a single take with no cuts.[1]
A 2017 film derived its title from this song. A portion of the tune of the song and some of its lines were reused in the title track of the 2017 film.[2]
Sriram Raghavan's concept for this song sequence - a blind girl playing the piano while a shootout happens around her - was inspired by the French short film "L'Accordeur" [English: "The Piano Tuner"] (2010). Raghavan used the same short film later as an inspiration for his film "Andhadhun" (2018).[3][4]
