Another musical question! Which actor and actress sang this song in a film in which they starred? They both sang for themselves in their early careers before playback singing became the norm.
Bonus points for the film name and music director!
A whole host of people, with madhu being first, knew that the singers are Ashok Kumar and Leela Chitnis, singing “Chal Chal Re Naujawan” from the film Bandhan (1940); music director credits to go Saraswati Devi (although I’ve also seen Vasant Desai and Ramchandra Pal credited). The lyricist was the inimitable Kavi Pradeep (also a good singer!).
