Singer Benny Dayal recalled missing out on the song 'Behka Main Behka' in Aamir Khan-starrer 'Ghajini' and said, "I was really sad." He shared that he was working as an HR in a corporate firm when he was offered the song. "I told sir (AR Rahman) that 'I'm at work and I'm unable to come...immediately for the recording'," he said.
