This immortal song from Sujata(1959) was written by Majrooh Sultanpuri and composed and sung by the great S D Burman. Both born on 1st Oct. This song was a background song.
The director of the film Bimal Roy gave a rough outline to Sachin Da for a song situation to be sung by a commoner. He wanted a song to sound as if it was straying off-tune, in spite of being in tune. Many singers were tried but ultimately Sachin Da himself finally recorded in his own voice. This was his second song in Hindi films sung after a gap of 12 years.
The situation was that the hero wanted to express his love for the heroine and also wanted to know her feelings. She being shy couldn't express her feeling in words, so to express her feelings Dada suggested a song in the Background.
Majrooh Sultanpuri wrote beautiful lyrics for this situation. The Hero and Heroine are in love They are on a riverfront and a boatman singing in the background expressing their love for each other. Their emotions are caressed by the gentle breeze. The unclear, dispersed light of late evening gives this 'Bhatiyali' song a perfect background. The excellent picturization. Their lips seem to be moving but the sound is mooted, the lyrics in the background expressing their feelings.
Surprisingly the scenes were shot well before the song was ready, in fact, the lyrics were written at the time the scene was being shot. Song recording was done after a few days. It was S D Burman singing solo after 12 years,
