Ratan Kumar (19 March 1941 – 12 December 2016)[1] was the screen name of the Indian born child artist who later migrated to Pakistan.
[1] After making the popular Indian movie Jagriti (1954), Ratan Kumar migrated to Pakistan in 1956, with his family, and remade the movie into Bedari (1957) (Urdu translation of Jagriti or awareness) and used the same old tune for a film song in Pakistan, aimed at igniting a similar emotion and patriotic zeal, among the listeners.
Aao bachcho tumhe dikhayen jhaanki Hindustan ki... (come children let us show you glimpses of India), is a popular Hindi film song of the 1950s.
[1] Ratan Kumar's success, as a lead actor, could not last long because his later films did not do well at the box-office and he eventually faded away.
[1] Ratan Kumar was living in California, in his old age, and was admitted to the hospital for pneumonia 10 days before his death on 12 December 2016.
