"Unless you are a good mimic, you cannot be a good playback singer and Kishore Kumar used to mimic voices left, right and centre. He was a very good actor himself and was also very observant. He observed heroes and internalized their characteristics. That's why he could sing differently for each of them. His songs will remain" - Anirudha Bhattacharjee, the co-author with Parthiv Dhar of 'Kishore Kumar; The Ultimate Biography' talks to Manjula Narayan on the Books & Authors podcast about the legendary singer's childhood in Khandwa, rise to stardom in Bombay, his doomed marriage to Madhubala, his deep relationship with SD Burman, and his run-ins with the government during the Emergency.
