I first heard this song in Sanjay Leela Banshali’s 2013 movie ‘Ram-Leela’, sung by Osman Mir and Aditi Paul and produced by the director himself; I was instantly blown away and thoroughly impressed to find out that the origin of this out-n-out Gujrati folk is a popular Rabindrasangeet named ‘Nabo borsha’ (New monsoon). In 1944, celebrated Gujrati poet and reformer Zaverchand Meghani translated this poem from Bengali to Gujrati along with some other works of Tagore. More surprise awaited when I listened to the recording of Hemu Gadhvi who first turned the poem into this Gujrati folk song; the singing style is so similar to traditional Tagorian music that until the language is registered in your ears, you will confuse it to be a Rabindrasangeet. The original recording is still available on YouTube.
Update: I took the liberty of adding the YouTube link of Hemu Gadhvi’s recording. The video I saw 2 years back is probably removed or claimed, but this recording is now available from more than one channels on YouTube, including one named ‘Hemu Gadhvi Trust’ who preserves works and memoirs of the legendary singer.
