I don't know if this has anything to do with it, but..:
At the Starmus festival on Tenerife this July (an astronomy & music festival - which, incidentally, also featured a concert by Hans Zimmer) one of the speakers was Joel Parker, principal investigator of the Rosetta/Philae mission.
He showed images of the comet and talked about how its shape resembled a head, neck and main body. And then he said, tongue-in-cheek: "And in case that concept is a bit too heavy for you...", and the next slide had an image of a yellow plastic duck superimposed on top of the comet.
He, he...if so, that's certainly a reference that will swoosh right past most people's heads, I think.
I thought maybe Vangelis had developped an 'old man quirk', like the pig toy our late, famous philosopher Arne Næss used to carry around in his last years.
