Sathyaraj: (Actor)

"When it comes to music, its MSV for me! I'm a great fan of the "King of Melodies", M.S.Viswanathan and I'm proud to say so."

Kamal Hassan: (Actor)

"MSV revived film music! Right from my childhood, MSV's melody has filled my ears and breath; Unlike Bharathiyar and Bharathidasan, three people whom I like, have got their due credits for their talents during their life-time itself. They are "Nadigar Thilagam" Sivaji Ganesan, "Mellisai Mannar" MSV and "Isai Gnani" Illayaraja; MSV revived film music through new trends in melody and tune. Its mystery that MSV still lives as a child at heart. He is a great legend in music!"

Cho.Ramaswamy: (Journalist)

"MSV's friendship is a pride for me! MSV is a child; But when it comes to Music this child will become a Giant; Let his unmatchable service to Music as a Musical Legend, continue forever, by God's grace! His numbers like Carnatic music, uplifted the human spirit."

Maestro Illayaraja: (Music Director)

“MSV has the capability to judge the talent of a musician just by looking at that person. The only reason for this is the blessings of Goddess Saraswathi, is fully showered on him. Wow! In how many songs has he melted my heart; Made me lose myself; Each song of his is a Gem, a Diamond, a Ruby; What can I give back to this man for filling my ears and heart with his music. Whatever I try to give him as a fee, it will be short of what he deserves. I stand like a poor left with nothing to give to Annan MSV, what he deserves; I can do one thing; If there is any that I have gained or earned so for through my music, I place the fruit and fame under MSV's feet and respect him; This is the only fair thing I can give him!”

Vaali: (lyricist)

"MSV laid a foundation which is the reason for my successful career as a lyricist, till today; I've never forgotten this nor hidden this; If MSV discovers that a poet has a 'fire' within him, he will go out of his way to recommend the lyricist to others in the industry; On Jan 1, 1963 I did not have money for food; I then joined MSV; On 31st of the same month, I did not have time to have food! MSV’s music has proved its values as it has not gone out of fashion since it first appeared."

Naushad Ali: (Composer)

“All his tunes have life in them. MSV has given me the status of "Guru", owing to his open-heartedness. This shows his great character. But the fact is I only learnt a lot from him. His tunes bestowed enthusiasm in me". Naushad was surprised by the speed of MSV's re-recordings. After seeing his recording, "For this piece, I would have taken 3 full days. How come you are able to produce music with such a speed and quality?!”

Kannadasan: (Lyricist)

“The best way to kill MSV is to give him poison while he is composing music. He will just drink it.”

K.Balachander: (Director)

“It’s a measure of the man’s character that now more than anything else he wants a chance to prove (once again) how good he is at stringing tunes.”
