We all know, Oscar winner AR Rahman will always have something exciting for his fans. This time, he made one of his lead singers to sing the female portion as well. Haricharan who has sung the Tango Kelayo song has rendered the female portion in the song. AR Rahman himself posted it on his social media page. His reply to a fan’s question read, “Dear Fazil, Thank you for your kind words. Its Haricharan himself with his vocal formant and pitch tweaked to modulate like a young sensuous female..we tried others but we couldn’t get this quality so retained the temp.”
