Hi Neal; Hmmm....the way I read the text on the site, this documentary does not exist yet. I think the person is soliciting funding to begin this project, and then approach several broadcasting outlets in the US and UK to see if interest exists. I hope it happens. Like most, I think the genius of Pandit Banerjee has been greatly overlooked.
That project has been "in the works" for a long time but nothing ever seems to come of it. BBC has a lot of Nikhil Banerjee footage but won't release it unless they get a lot of money......would be a nice thing to see though, wouldn't it?
