Amitabh Bachchan is rejoicing the opportunity of singing Rabindranath Tagore's iconic song "Ekla Cholo re" in director Sujoy Ghosh's new film "Kahani", also starring Vidya Balan.

"May I just say that singing Rabindra Sangeet for the first time was the greatest revelation. The beauty of the language, the lyricism of the tune and its 'dhun' (music) are outstanding," he wrote on his blog bigb.bigadda.com.

"This particular, world famous number "Ekla Cholo", expounding to all that if no one came to you on your calling, walk alone!! And what a fabulous song has been incorporated by Vishal-Shekhar. Truly awesome and worthy of all award.

"Singing for the track today you discover how inadequate you are to handle something created by Gurudev Tagore. Not just in words but also in its tune. It is by far one of the most unique compositions in the world of music. And being associated with it in some capacity has been nothing short of an honor," he wrote.
