Actually Amitabh has sung Ranbindra Sangeet in Sujoy Ghosh's upcoming Kahaani. Rabindranath Tagore number 'Ekla Chalo Re' is for sure a challenge to Big B. “I was a little wary because not being a professional singer, any kind of singing is difficult and this was a Rabindra Sangeet in a language I was not conversant with," Big B wrote on his blog.
He said, “I plan to re-record it, again and again, till I get it right. Otherwise not just by Bengalis that considers me as jamai babu (son-in-law), my head will be chopped off in my own house." Poor Mr B seems terrified. Mr B it would be better if you take tuition classes on Rabindra Sangeet.
