This one's from Moby Grape's disastrous 1971 "comeback" album on Warner Brothers. I say disastrous because (although there are actually a couple of fun songs) the sole contribution from the group's best songwriter, i.e., Skippy, and thus pretty much everybody's reason for listening at this point, turned out to be...an instrumental.
Titled "Chinese Song."
Which is five minutes or so of exactly what you're afraid it might be from the title.
If I'm in the right mood, this actually strikes me as kind of funny, and for what it's worth, it's at least listenable. Still, and I can't recall what my take on it was when it first came out, it probably should have been a clue to fans that its auteur had pretty much lost his marbles.
