Kumar Sanu started his playback career in 1986 with a Bangladeshi film Tin Kanya, which was directed by Shibli Sadiq.
In 1987, music director and singer Jagjit Singh offered Sanu the chance to sing in the Hindi film Aandhiyan movie released in 1990. In 1989, Jagjit Singh introduced Kumar Sanu to Kalyanji Anandji at their residence Vimal Bunglows in Mumbai. On their suggestion, Kumar Sanu got his name changed from Kedarnath Bhattacharya to Kumar Sanu, because his voice and singing style was much influenced by Kishore Kumar.
Anandji shared this story in the Show Jeena Isi Ka Naam Hai hosted by Farooq Sheikh. Sanu then relocated to Mumbai, where Kalyanji-Anandji gave him chance to sing in the film Jaadugar.
Sanu went on to work with composers including Naushad, Ravindra Jain, Hridayanath Mangeshkar, Pt. R K Razdan, Kalyanji Anandji and Usha Khanna.
