There was a solo rock type of a song (a la "ennadi meenakshi", "sorgam madhuvile") in Kalyanaraman. They used to advertise the song in Vividh Bhartai prior to the release of the movie. However, the song didnt make the movie or the album.

A slight twist to this subject - there is a title song in "Mullum malarum" - 'Maane" sung by IR. It is a great song. But since it was not in the album, I dont think it got the recognition it shoudl.
