The Interviewer was Biju Narayanan and they were talking on the modus operandi of normal music direction - lyrics first, music after and music first , lyrics after(which is normally followed these days).
The film they discussed was Mizhi Randilum and the song was "Enthinaayi Nin Valamkayyin..". According to Raveendran , Ranjith, the director asked him to compose a tune where a sister sings a song for her younger sis whose marriage is fixed. The first thing Raveendran thought about was the same situation in an old movie of music director Baburaj and the song , "Annu Ninte Kavilithra Thudithitilla..." and when the lyricist Vayalar Sarathchandra Varma-Vayalar Ramavarma's son- called Raveendran to ask about the mood of the lyrics, he said to follow the same theme of the Baburaj Song. So he wrote "Enthinaayi Nin Valamkayyin.." on Babukka's tune - (Those who know the tune and lyrics try singing it - it is a perfect match) and handed it over to Raveendran.
Obviously Raveendran cannot put it in the same tune. And he created a wonderfull high pitch music for "Enthinaayi Nin Valamkayyin.." which was sung by one and only K.S Chitra. And man what a song that is.
So one song that can be sung in two tunes. Absolute Raveendran Magic. Oh God why did you pluck him away so early, why you didnt allow us to hear more Raveendra Sangeetham.
