The lyrics of the song Yeno Kuviamilla Oru Katchi Pizhai by Madhan Karky in the film Ko, which was featured in the movie’s teaser has already struck a chord. Madhan Karky Vairamuthu, an assistant professor at the Anna University stepped into writing Tamil lyrics by chance. His tryst started with writing the lyrics for Irumbile Oru Idhayam, the hit song in Endhiran.
Having good knowledge about Robotics and artificial intelligence, Madhan was working as a technical co-coordinator with Shankar and writing lyrics just happened. Madhan is no novice in this area as he has already written for a Tamil movie produced by the Singapore Government titled Guru Shetram and draws inspiration from his father and famous lyricist Vairamuthu. He has also written lyrics for the movie Engeyum Kaadhal.
