Dave Arkin's lyric (Dave is Alan's father) is in my opinion the most acceptable.

I have changed it a little.

"All the colors, yes, the colors we see in the rainbow and all of the flowers,
All the colors, yes, the colors we see in the rainbow that follows the showers,
All the colors, yes, the colors of people now taking their place in the sun.
All the colors abound, the whole world around
For people when freedom is won.
All the colors abound, the whole world around
For people when freedom is won."
