Some days back, in celebration of the birth centenary of Mohammad Rafi, I posted a list of ten Rafi songs, picturized on ten different actors. Each of those men—Dilip Kumar, Dev Anand, Shammi Kapoor, even Johnny Walker—were immediately recognizable. Big names in their own ways (yes, even Johnny Walker, whom I personally think of as the greatest comedian to have lit up the Hindi silver screen). But even as I was compiling that list, I was thinking of all the many other times I’ve listened to a Rafi song, and have been unable to put a name to the man who’s lip-syncing to his voice.
