 Earlier reports suggesting that one of the song would feature Yuvan Shankar along with his father Ilaiyaraaja's vocals, and that Andrea Jeremiah had sung another song, turned out to be false.Further Venkat Prabhu disclosed that S. P. Balasubrahmanyam and Shankar Mahadevan were approached to render one number in vain, with the former declining, explaining that the song was too high-pitched for his voice, and the latter being unavailable.The "Machi Open The Bottle..." song and the club mix of "Vilaiyaadu Mankatha" were notably orchestrated by Venkat Prabhu's brother Premji Amaran.
