"I said no way, Abosheshey. Not again," Rupa said recalling director Abhijit Dasgupta and music director Indradeep Dasgupta persuading her to sing Tagore song 'Achhe Dukho Achhe Mrityu' (there is grief, there is death) in "Asbo Aar Ek Din".
"Your wife and sister may sing better than me. But since it is Rupa Ganguly you will say ooh and aah," she told PTI quoting director Aditi Roy and script writer Neel in "Abosheshey".
In "Abosheshey", Rupa had sung the timeless Tagore number 'Dure Kothay Dure' on the anguish of a mother not meeting her son for days.
"But singing Tagore song brings solitude. And I enjoy singing without any prodding, because I am not a good singer," the Padma Nadir Majhi and Yuganto actor said.
The song, which was originally recorded without instrumentation and is the title track, was later given some background music.
"Rupadi is a natural singer. And due to her busy schedule perhaps the sense of fatigue was traceable in her voice when she came for recording," Indradeep said.
