I am in a fix

Last week my company members made a presentation to make of a tool to one of our Business clients. Having worked with the Business client for sometime now, he and I were generally chatting and he mentioned that he could hardly follow the presentation made because of the thick Indian accent.
I was confused if I should let the senior person know that his accent was not followed in the meeting or should I let the potential opportunity to expand business slip by?
What would you do?

UPDATE:
As you all agree it was a tricky situation for me. Fortunately the senior person who gave the presentation doesn't work in the same place that I do. I met with another person who works locally and told him that the client felt that our presentation was too quick for him to follow and that he could not understand and appreciate most of the capabilities of our tool. So I was going to arrange for another meeting with the client where we could walk over the tool. This was well received ... and tomorrow we have another demo with the client.
