Ronit has lent his voice to the title track of the film.

"I didn't know such a good singer was growing in my house. I had seen him playing guitar, sometimes humming some tune, but I never lent ear to that very seriously. He has a small band. Once he was performing somewhere and I decided to go and see what he does. To my surprise, he was singing so well that people were clapping and whistling on his performance. He was singing very well," says the proud father.

"I made him sing in a couple of my ads, he was fantastic. Anandh (music director) was looking for a fresh voice, one who could sing in high pitch and modulate well between the notes. He chose him for the song," Sarkar said in an interview.
