I find it puzzling that they would be chosen in 1919 before they had accomplished anything of note or gathered a world wide following. Makes no sense and could be likened to a contestant turning up to audition for American Idol or something and being told "no, no don't bother singing us anything you've won!"
It would make way more sense to me for them to claim official or rather celestial endorsement now.
This point alone helped prove to me they are not nor ever were "chosen."
