Thanks for your interest -- and I'm pleased to hear your uncle is also interested in being in India at this time. Unfortunately, there is really no way to have anyone else join the delegation anymore.
I admire what you did in Exeter, by the way. Well done.
Julian Bond, I understand, required a $10,000 fee, so it would be VERY costly. My preference would be to chose a topic and then get the best people, even if all of them are not well known. For example, I think that there would be a lot of interest in a symposium on the relationship between Gandhi and King.
