Once, a long time ago, a friend told me that he had seen James Taylor in concert, and that during "Fire and Rain" he (Mr. Taylor, not my friend) sang "look down upon me Bokannon, you gotta help me make a stand ..." (sorry if I misspelled "Bokannon", it's been awhile. Bokannon, as I recall, was a religious figure, or deity, in "Cat's Cradle".) Apparently Mr. Taylor is, or at least was, a Kurt Vonnegut (sp?) fan, so he might well slip a Vonnegut reference like "granfalloon" into his work in one way or another.
