The music maestro A.R. Rahman directing Alia Bhatt on her debut song ‘Sooha Saha’.

This is what Rahman has to say about the experience –  “We have this lullaby, Sooha Saha in Highway.Imtiaz said Alia has a great voice and I didn’t trust him.Then she learned the song and sang to me and I was pretty impressed with her natural ability too. We guided her a little bit to perfect the singing. She did it twice and then we got it almost right and now it sounds great”
