"Somewhere over the rainbow, way up high," Well Elphaba didn't really know if it was way up high, but she'd never been, so she had to assume.
"There's a land that I've heard of once, in a lullaby." Really, it was half true. Turtle Heart had told her mother about the Other Land, and who could help if she was listening?
"Somewhere over the rainbow skies are blue," Elphaba imagined the place to be bright and never cold or rainy.
"And the dreams that you dare to dream really do come true." Like being de-greenified, but Elphaba kept that to herself.
"Someday I'll wish upon a star and wake up where the clouds are far behind me." Where everything is warm and no there is rain to melt her.
"Where troubles melt like lemon drops," Lemon drops were not Elphaba's favorite, nor did she know anyone who particularly enjoyed the sour candy, but they practically puddled in her hands.
"Oh way above the chimney-tops, that's where you'll find me." She could only go with the flow of the song, as she had already said it was way up high.
"Somwhere over the rainbow bluebirds fly. If birds fly over the rainbow, why, then oh why can't I?" On the wing over the rainbow, just like a green bluebird, Elphaba could imagine herself flying.
"If happy little bluebirds fly beyond the rainbow, why can't I?" Elphaba's hands unconsciously spread, as if to help her take flight.
