When we meet her at the Dharma office, Alia Bhatt - looking sprightly as always - can barely conceal her happiness after having watched the cut of Ghar More Pardesiya, the first song from Kalank. "There was no scope of going wrong with this," says the actor.

Remind her that her last classical dance piece was in Abhishek Varman's 2 States (2014), and she nods, "He has the habit of pushing me out of my comfort zone. It was a difficult and crucial song for me. While I trained in Indian classical dancing for nearly a year, I dedicated two months to this particular song. Pandit Birju Maharaj helped me crack the expressions. I consulted him a week before we shot the song."
