You can safely say that NT played second fiddle to Gemini in Unakkaaga Naan. Gemini has longer presence in the film. Film went unnoticed unfortunately.
To me its the best from Gemini, very soulful performance. Watch him in Iraivan Ulagattai Padaittaanaa (singing to ailing Nagesh, who too was good), his performance in this song was even better than the famed and overpraised Nilave Ennidam in Ramu.
