The song was famously performed live on January 27, 1963 by Lata Mangeshkar at the National Stadium in the presence of Prime Minister Jawaharlal Nehru in New Delhi on account of Republic Day (26 January) 1963, just two months after the end of the war. A copy of the soundtrack spool was also later gifted to Nehru on the occasion. The song is said to have moved Nehru to tears.
