This is a classical music based song from the movie Ambikaapathi featuring Sivaji, Bhanumathi, Nambiyar, Nagaiyah and others. No better tribute to TMS and Sivaji than this comment on youtube about this song, "TMS's unique performance with his solid voice. Excellent. Thanks for posting this. Of course, Sivaji Ganesan gives the impression that he is the one who has actually sung the song!" by nathenpeter7. The classical music knowledge of some the people who post comments is really amazing. If you go through the comments you can see how these people have pointed out the different raagaas used in this composition in the different parts of this song. P Bhanumathi is supposedly the only actress to have addressed both MGR and Sivaji by their names in those days!
