I am a bit of a wierd one, though ,as I'm not a big fan of their "older" stuff, such as Obscured by Clouds and Ummagumma. I still have all of their albums, but I don't listen to the older ones much.
Also, the song is both ways, depending on which version you listen too, and which verse. There are several recordings of it with slightly different variations.
As Primus said, "If you studied your Floyd properly, you'd know that pigs could fly."
