Yesudas recorded his first popular song "Jaathi Bhedam Matha Dwesham" (music: M. B. Sreenivasan) on 14 November 1961. The singer considers those four lines he got to sing to start his career in films as a huge blessing as it was written by none other than Sree Narayana Guru, the most respected saint-poet-social reformer of Kerala. The film was Kalpadukal (1962), based on social reform during the life and times of Sree Narayana Guru. He associated with popular singers of those times like P. Leela, Santha P. Nair, K. P. Udayabhanu, S. Janaki etc. and lyricists like P. Bhaskaran and Nambiyath. He sang the lines of poet Kumaran Asan for this film.
