Veteran singer Subir Sen, known for his work in "Chhoti Bahen", died of lung cancer here on Tuesday, hospital sources said. He was 81.
Sen, who is survived by his wife and daughter, passed away at 8 a.m.
He was undergoing chemotherapy and was admitted to the Belle Vue Multispecialty Clinic many times since May.
Some of his well-known songs include "Dheere chalao zara" with Lata Mangeshkar in "Aas Ka Panchhi" and "Humein un rahon par chalna hai" in "Masoom".
In the 1950s, Sen added a unique romantic touch to hit Bengali songs such as "Monalisa tumi ki bolona".
West Bengal Chief Minister Mamata Banerjee condoled his death.
"Saddened at the passing away of legendary singer Subir Sen. He is our Banga Bibhushan. He will always be in our hearts," she tweeted.
