C Ramchandra started his career as an actor in early 1930s, he acted in the movie "Naganand" (1935) produced in Marathi and Hindi under the same title, the film was directed by Y V Rao, a South Indian and father of "Julie"/Chattakkari fame Lakshmi. The film miserably flopped at box office, It was based on a story from Kathasarithsagara.
I believe his music career started not in the north, but in the south. His first music composition was for the Tamil movie, "Jayakkodi" produced in late 1930s, and he became popular with his second Tamil movie, "Vanamohini" (1942). In Vanamohini he sang also for the hero, M K Radha. His songs from Vanamohini became hits, with good Tamil diction he sang the songs.
In Tamil, another super musical hit to his credit was "Vanjikottai Valiban" produced in 1950s by Gemini films, which was remade in Hindi as "Raj Tilak" The dance competition in the films featuring Padmini and Vyjayantimala remain a wonder in cinema.
