In 'Badtameez Dil' from Yeh Jawaani Hai Deewani, Ranbir's footwork seems inspired from choreography in songs like 'Aaja Aaja Main Hoon Pyaar Tera' (Teesri Manzil, 1966) and 'Baar Baar Dekho' (China Town, 1962). The makers of the film, however, maintain it's only a coincidence. "I don't know if we can call it an ode to Shammiji; it wasn't a planned move. But now, when we look at some of the moves and Ranbir's mad energy, the similarities can't be ignored.

I think people see the connection because Shammiji also possessed unparalleled energy when it came to dance," says director Ayan Mukerji. Shot over five days, the song that has been choreographed by Remo D'Souza, is also special because Ranbir brought in his 30th birthday during its shoot. "I didn't have any song-and-dance number in Wake Up Sid (2009), but I always wanted to explore shooting one. So I am really happy with the response," adds Ayan.
