Well-respected theatre personality T.K. Shanmugam had been using Bharati’s songs in his theatre productions from as early as the late 1920s. Shanmugam, following the success of his play Bilhanan (1948), based on the legendary eleventh-century Kashmiri poet of the same name, decided to turn it into a film. A song from Bharati’s Kannan Pattu, ‘Thoondil puzhuvinai pol’ (Like the worm in a bait—a song on the pining of a lover), which Shanmugam had used in the play, was to be included in the cinematic version as well.
