I've listened to that a lot, and always felt he was saying "One who passed through" which I think makes total sense. He seems to be telling the band what the next song is, and he calls it "one who passed through" (a line in the chorus) instead of the actual title of the song. He does that a lot onstage, when he's giving a cue to the band, as a shortcut to the title of the song.
