Hindi film songs, in the context of being part of films, have always struck me as rather unreal. Of course it’s a miracle that people in cinema (and that’s not just Hindi cinema, but almost any cinema that produces musicals) break into song at the drop of a hat. How do they think up lyrics on the fly? How do they think up a tune as they go along? How can they dance and jump around and not run out of breath while singing?

Let’s say that’s all artistic license, and that we need to accept it (we do). But what happens when there’s no way a song could be possible? A duet, for instance, sung perfectly in tandem—the tune the same, one verse completely responding to the previous one, even the voices sometimes blending together? —when the two people supposedly singing the song are nowhere close to each other? One is one part of town, the other in another. Or even, in some cases, not even in the same town. Impossible, that’s what I call such duets.
