He ran away from home with dreams of finding his fortune in Singapore, but ended up working in drama troupes such as those of Jagannatha Aiyer and Nawab Rajamanickam Pillai.
Films such as Ezhai Padum Padu (1950), Kanchana (1952) and Malaikkallan (1954) helped him to consolidate his place among the front-ranking composers of the decade.

When MGR turned producer and director with Nadodi Mannan, he invited SMS to compose the songs, along with N.S.
