Good points, all.

Other things, interesting: Chinese People Fighting in the Park is probably a reference to Vietnam, "we tried to help them out, no one appreciated that." I heard somewhere that it could also be a reference to Tai Chi -- the meditative stretching exercises, that kind of look like martial arts. Obviously, anyone trying to "help out" someone doing Tai Chi is going to upset them.

The King of Cuba could be a reference to the theories that Castro put the hit out on Kennedy -- after Kennedy had tried to assassinate Castro a couple times. That action cemented Castro in his leadership roll - ie. crowned him the King (as opposed to President -- a president leaves office, whereas a king stays until he's dead).

Could "the camp" in the first line be Boot Camp? A reference to the draft?

I think the Purple Toupee and Gold Lame is a ref. to styles -- the whole "hippy" culture, be free, conform to our non-conformity. To support this, "we're on some kind of mission," almost sounds like the author has no idea why he's protesting or dressing up - its just "some kind of mission," but whatever the reason, he's obligated to do so.

On second thought, I think maybe those last three lines sum up the song. Its about a former 60's protestor who is so burnt out, that he has no idea why he was even protesting at all -- and he can't even get the events right. But it was a mission...
