A popular number from the Assamese movie Bhagya. Bhagya was remake of the hindi movie Taqdeer released in 1967. Apart from the story, music of the movie was also remade in Assamese and Dr Bhupen Hazarika made those songs immortal with his golden touch. The original of this song "Jab Jab Bahar aai" was sung by Md Rafi. The lyrics was by Anand Bakshi and music by Laxmikanth Pyrelal. The remade was so wonderfully done by Bhupen Hazarika that the song now takes an original place in the listeners' heart.
