"In a conversation with lyricist Pulak Bandyopadhyay, Burman had mentioned that the second line of the national anthem—Punjab Sindh(u) Gujarat Maratha Dravid Utkal Banga—had inspired the line, 'Humne to Jab Khushiyaan Maangi'.
"The reference to the national anthem is so subtle that unless someone points it out, it is next to impossible to spot a similarity."
Pyaasa had 10 songs, two solo songs were sung by Geeta Dutt, and one duet of Geeta Dutt and Mohammad Rafi, all the other were solo of Rafi except this song. In fact, Guru Dutt wanted this song to be sung by Rafi but Burman Dada insisted on Hemant Kumar. Dada knew that this song suits Hemant Kumar, one of the highlights of this song was the aching frailty of Hemant's rendition. A major argument took place between Guru Dutt, composer Burman Dada, writer Abrar Alvi, and Geeta Dutt. Finally, Dutt, who remained unconvinced, had to give in to the pressure.
This song was picturized on Guru Dutt. He is leaning against a bookshelf, wearing a white shawl, stretching his hands, a wry smile even though he was deserted. Singing in a small gathering organized by his employer Rehman, where he meets his ex-girlfriend Mala Sinha, who abandoned him for wealth by marrying none other than the man currently employing him.
If you listen carefully you will find a piece of very light music is being played in the background. Burman Dada had arranged the song with delicate piano notes, surprisingly np piano is shown on the screen.
Once Burman dada was asked why this song had such little music. He replied that the poetry was the hero of the song and had to be showcased. And it’s true, the soft tune in the background pushes Sahir Ludhianvi’s words to the forefront. Unfortunately, this was the last song of Sahir composed by Dada Burman. They never worked together after this song and film.
