Veda lived in Ceylon (now Sri Lanka) in the 1940s.The music here was inspired by the Sinhalese Baila music which was a kind of fusion music inspired by the Portuguese colonialists during the 15th century. This song was hugely popular amongst the Sinhalese community in Sri Lanka and they took it almost as their own despite the language being different.The Goans in India too played similar music As a dancer, S.S.Rajendran was the best amongst the top Tamil hero actors, far better than M.G.R, Sivaji Ganesan and Gemini Ganesan. Otherwise,this song should have gone to comedian Chandrababu who also lived in ri Lanka and knew the Baila music and the Baila dance.
