Childhood, they say, is one of the rare joys of life. William Shakespeare called it the first age of man. Marcel Proust constantly sought to return to it. On Sunday, the duo of composer Shantanu Moitra and lyricist Gulzar will present on stage one such ancient poet — Rabindranath Tagore. They will shed light on his poems on childhood, innocence and life through their concert, Citi NCPA Aadi Anant: Tapur Tupur: Bachche, Bachpan aur Bachpana.

Easier said than done. A poet, playwright and composer, Tagore’s poems and songs have entrenched themselves in Bengali culture through Rabindra Sangeet. Moitra grew up with the poet in more ways than one, yet he says, “It starts with Gulzar’s love for Tagore. For me, it was a genetic acquisition. For him, his love for reading stems from Tagore.” It was a translated edition of The Gardener and Gora that famously sparked the lyricist’s thirst for literature as a child. Over the last two decades, the veteran has dedicated hours to translate the bard’s poems from Bengali to Hindi.
