The other famous song of the same year from the same combination was 'vaan nila' from 'Pattina Pravesham' To me though, that voice modulation also means a change in tone but that does not affect the song. And all that laughing in the middle was clearly his territory. You can hear him doing all the voice modulation required for what is essentially a sad song. In this song you can observe a SPB who is quite sure of himself. K Balachander - MSV - Kannadasan - SPB combination gave this song from 'Avargal' (1977). Let us now look at some MSV SPB melodies of the late 70s. MSV also gave singing opportunity to singers like Jeyachandran and Jolly Abraham. Yesudas also has some lovely numbers with MSV during this period. MSV during those times made both Yesudas and SPB sing many songs. His combination with Balachander produced some melodies which are popular to this day. What I was talking earlier was the percentage of good songs that he gave, which was getting lower. MSV though gave some amazing numbers in this period. Like Chakravarthy in Telugu, they too would churn out tune after eminently forgettable tune. Of these Shankar Ganesh would go on to score for lot of films. The other upcoming music directors at that time were Shankar Ganesh duo and Vijaybhaskar. The songs too were middling and forgettable. If you look at the list of films that MSV did between 19, you will surprised that you have never heard of many of movies. Let me say, his form became uneven in those time. M S Viswanathan who was the dominant music director in Tamil was slowly losing his form. Raja's coming to the scene happened at the right time.
