News of Dey's passing away shocked thousands of his fans, especially the music industry and the million-strong Bengali community in this tech hub.
Dey was in the same hospital for about 20 days in May a week after West Bengal Chief Minister Mamata Banerjee honoured him May 1 with Bengal's Vishesh Maha Sangeet Samman award in recognition of his yeomen service to the world of music and the film industry for over seven decades.
