I did my fifth standard in a school in Nagercoil. On Sunday afternoons, after lunch we used to hear music from Ceylon radio. The voice of the radio jockey will be musical and they will pronounce crystal clear Tamil.
Tamil hit songs countdown(like Superhit Muqabla) was aired on the radio at that time(1983). Devathai Ilam Devi song from the movie Aayiram Nilave Vaa became the number one song in the ranking. And on all the following weeks it continued to top the list. If i am not mistaken, i think the song was number one for more than a year. Kudos to Ilayaraja( music director), SPB (singer), and Karthik (Actor).
