For all the videos I've seen, there're only two versions which Odette/Odile is danced by two dancers: the famous Ulanova/Dudinskaya's version in "Stars of Russian Ballet" ,and the Pavlova/Kunakova's version in the 90s.
I'm wondering why aren't the roles danced by one ballerina?
suck at English, hope you guys can understand what I'm talking about, thanks in advance!
