As Long as I Can
Stevie Wonder's version is rock solid, and has been cover from Sister Sledge to Jean Luc Ponty, but I love the depth and energy that George and Mary bring to this.
The song implies that the love the singer has for the object of his love will never diminish, as he says that he will love until the physically impossible becomes true. The impossible feats include: rainbows burning the stars out in the sky, oceans covering the tops of every mountain, dolphins flying, and parrots living at sea, dreaming of life and life becoming a dream, day becoming night and vice versa, trees and the seas flying away, 8×8×8 equaling 4, this day becoming the last day, the Earth turning right to left, the Earth denying itself, Mother Nature saying her work is through, and "until the day that you are me and I am you." One interpretation is that this is a lover singing to his mate. Another interpretation is the song is about the endless unconditional love the Judeo-Christian tradition God has for the listener and the singers part in that. A third interpretation is that it is about the singer's unconditional love for humanity. The verse that begins with "We all know sometimes life's hates and troubles..." would seem to preclude the first interpretation, and the second interpretation would seem precluded by the lyric, "As today I know I'm living but tomorrow, Could make me the past but that I mustn't fear ."
