Hi, schizophrenic, yeah, that is my best guess as well. As I mentioned in my post, I see the 50s as a very disingenuous time, with hollow, hateable values. And Bowie saying "goodbye" to all that in the personage (or, is it horse-anage?) of Mr. Ed makes some sense.
I also wonder if it has a connection to a painter named Edward also, though, because Bowie has a knack for duality in his referential work.
I'm also specifically baffled by who "the fellows with no heads" are. Still trying to untangle all this.
I'm Bowie's "Publicist"
