Sure they do, it's just a little unusual:
"You don't belong, where the humans eat,
you don't belong, don't belong to me"
Under this interpretation, it's about someone he had a lot of friction with, someone who had trouble relating to other people properly (and as result was quite unpleasant at times). Spiritually, he didn't belong somehow... and when he passed away it made an odd kind of sense. So Willy wrote a song about him, and rather than twist it to pretend this guy was some all round well-loved chap (as we have a tendency to do), he talks about honestly about his flaws, but uses it to say that he "didn't belong to us"; it's very poetic, and a proper tribute to his character.
Of course, that's just an interpretation. But there's no reason why it doesn't make sense. In fact, the song has had a lot more power for meever since I arrived at that perspective.
