The song is a reproduction of an original song, which makes it different and the same as the original. So too, Derek and Sara are just a man and a woman in love who want to express this emotion physically. What makes them different is simply their color, illustrated to us by the title of the song, "True Colors-. .
The sequence of sexual seduction is revelatory about historical shifts in ideology from 1987 to 2000. Baby does not know how to dance but Sara knows ballet. If dancing serves as a metaphor for sexuality than we can assume that Sara knows a little bit about sex, but has not been exposed to a different kind of sexuality, a sexuality represented by hip- hop. Both women are learning about their sexuality while they learn about dance, but they do so only to become spectacle "as part of a performance that will be seen by many. Significantly Sara's performance is her performance alone, reflective of a more current ideology that women's sexuality is not only a reflection of the man she is with, but also of her own creation and identity7. In Dirty Dancing, Baby is helping Johnny and her learning to dance only serves him. After both performances are successful both Sara and Baby choose to privately consummate their sexual feelings with their dance partner. Like a wedding, these women are tied to these men by the spectacle of public dancing and can now give into their sexual desires in private. Both women operating on the higher end of class/race, as determined in a dominant class ideology, must invite the men into their beds because men of lower classes or a different race would probably fear the cry of rape before they would initiate the sex act. There are some who might argue this point and assert that women are still very much tied to men in order to define their personal sexuality. That may be true, however in this analysis, I think it is clear that the film is trying to present an idea to the audience that Sara is taking control of her own destiny, both by her choice of trying out once again for Julliard, and her choice of Derek as a lover.
