Janos Gereben on Arlen and Mercer's "Come Rain or Come Shine":

>Just as she sings Isolde's killer role with a voice that flows from her
>naturally, inexorably, she sang the Johnny Mercer text in Arlen's simple,
>appealing harmonies from the heart, without a smidgen of artifice.

"But I'm with you always, I'm with you rain or come shine."
