With the help of my Kolkata based friend, I came to know that ARJOE Entertainment, the company, which published Chhotto Ei Monta MP3- the Bengali version of Chhoti Si Asha, is currently not operational in Kolkata. So there is very little hope left to get the same.
Is there anyone in the group who hails from Bangladesh? As far as I remember, the song was used in a Bangladesh movie and there must be a soundtrack for that movie. If anybody has it, please upload it in any sharable folder. Durba
