Oh wow! I just realized too, Bachelorette and Alterna are very same-ish video wise! But I love Bachelorette, thats one classic song I will never forget, which I could find Homogenic.
I think he's referring to that Britney video called Anticipating which also had some sort of stage/play/dolls feel. Except I only saw Britney's live version and the set was all puppetty.
