Master Sgt. Caleb Green is the only Master Sgt. I see listed HERE, BillD.

I just heard a snippet of a rebroadcast of Obama on Meet the Press in Dec., just after I'd heard Pete singing, today. The following lets me know we will be seeing a lot more of this coming together with Obama leading the way (my emphasis):

MR. BROKAW: Who are the kinds of artists that you would like to bring to the White House?

PRES.-ELECT OBAMA: Oh, well, you know, we have thought about this because part of what we want to do is to open up the White House and, and remind people this is, this is the people's house. There is an incredible bully pulpit to be used when it comes to, for example, education. Yes, we're going to have an education policy. Yes, we're going to be putting more money into school construction. But, ultimately, we want to talk about parents reading to their kids. We want to invite kids from local schools into the White House. When it comes to science, elevating science once again, and having lectures in the White House where people are talking about traveling to the stars or breaking down atoms, inspiring our youth to get a sense of what discovery is all about. Thinking about the diversity of our culture and, and inviting jazz musicians and classical musicians and poetry readings in the White House so that, once again, we appreciate this incredible tapestry that's America. I--you know, that, I think, is, is going to be incredibly important, particularly because we're going through hard times. And, historically, what has always brought us through hard times is that national character, that sense of optimism, that willingness to look forward, that, that sense that better days are ahead. I think that our art and our culture, our science, you know, that's the essence of what makes America special, and, and we want to project that as much as possible in the White House.
