Salil Chowdhury was a famous Hindi and Bengali composer, poet and a playwright. He was born on November 19, 1922 and died on September 5, 1995, just before his 73nd birthday.
He is widely recognised and acknowledged in the Bollywood as one of the most prodigious composers ever. Here's one of his songs rendered by Lata Mangeshkar in film, Parakh. But before that a story about his own singing.
Once, Salil sang an emotional Bengali song on Bimal Roy's request. After the song was finished, Salil found that Lata had fainted. Later Lata told him - "I was so overcome that I couldn't control myself".
Salil used to say - "Almost all my songs that require a female voice have been sung by Lata. I've rarely felt the need to turn to someone else."
