Har Mandir Singh 'Hamraaz'

He was born and brought up at Kanpur [India]. During his matriculation [1966-67], he started listing the songs of his choice. In the absence of any authentic book which could provide him full credits of all songs of Hindi films, he was prompted to compile such information.
After completing graduation in June 1972, he joined the State Bank of India, Local Head Office, Kanpur in July 1972. He published his first Hindi Film Geet Kosh volume in January 1980. Having said goodbye to the State Bank of India on 30th November 2011 upon his natural retirement, he is now happily devoting his full time for the remaining compilation work.
