Yeah, I needed something to characterize him a bit more, and adding the music and the New York thing worked. That and throwing in some of the civil rights stuff and generally keeping the situation in America in mind. Vietnam wasn't the cause of everything going on in terms of social upheaval in the era, but it certainly added to it. I wanted a little more depth than the first character offered and it makes sense that, given the sometimes ugly racial politics of Vietnam that could flare up, that the MG guys might be the same 'color' and in a sense, probably think that they can rely on each other the best out of the rest.
