"I wanted to sing the song because it is his movie. I wanted to be a part of it," Rahman said. Sachin, who was also present at the event, said he did not give any inputs to Rahman for the song. "What can you say standing in front of the Mount Everest? He is the ultimate, right?" he said. Rahman said he had created 14 versions of the song before zeroing on the final one. The song has been sung by Sukhwinder Singh.
