Ramkumar Chatterjee is regarded as the repository of Bangla Puratoni Gaan (old Bengali songs). It was he who popularized the genre of Bengali Baithaki songs. Hailing from a strong musical background as his grandfather, himself a classical singer, wanted young Ramkumar to learn tabla as it would help him to develop an ear for musical notation. However, the prized moment came later when he got an opportunity to accompany Kazi Nazrul Islam during a public meeting held by Netaji Subhash Chandra Bose at Hedua in north Calcutta. Sharatchandra Pandit popularly known as ‘Dadathakur‘ appointed him as a singer at the radio station after a short voice test, which he cleared, and started singing. He was given five rupees per song.
