This song has a long internationalist history. Written by the Turkish poet Nazim Hikmet, it was translated from English into Bengali by Subhash Mukhopadhyay, one of Bengal's foremost leftist poets. Several versions soon existed, in the form of variants of a song. Ajit Pandey sang the version closest to Mukhopadhyay's translation. This is a different version.
A note to non Bengali audiences. Hikmet had written "Negro" back when he worte it, and Mukhopadhyay translated it as Negro. A tribute to Paul Robeson, this song is in no way meant as an insult to African Americans.
