NEW DELHI: Double Oscar winner A R Rahman, who composed the Commonwealth Games Theme Song 'Yaaro India Bula Liya', today said he was "sorry" if this number has let down anybody after it attracted criticism in some quarters.

"I am sorry if I have let anybody down on this but definitely I am proud of the composition and the anthem," the famed composer said.

Rahman said it is difficult to satisfy everyone but "I will try my best" in future.

Rahman said he has realised that next time he should be more careful about testing it out on every generation-older, younger.

He however said there was a positive reaction when the theme song was tested on people from different nationalities.

"Of course, some people did not like it and it became a huge controversy," he said.

Rahman said in his view the number went "great" during the opening day ceremony. "It had lovely feedback from Australia, England and all those places, who had not heard about controversy and they loved the song," he added.
