The famous and cult song 'Ek Chatur Naar' from the super-hit movie 'Padson' (1968) is apparently a copied version from a different old Hindi movie.
Featured on Kishore Kumar, Sunil Dutt, Mehmood and Saira Banu, the well-known competition song was composed by R D Burman, and was sung by Kishore Kumar, Mehmood and Manna Dey. Well yes, this RD Burman's composition is an alleged copied version of an old Hindi movie, which was released in 1941.
