Robert Heinlein wrote a story called "The Green Hills of Earth which features a blind, space-going, accordion playing folksinger named Rhysling. The story title is also the name of one of his songs. Heinlein included snippets of the song including the closing line: We pray for one last landing/ On the globe that gave us birth/ Let us rest our eyes on the fleecy skies/ And the cool, green hills of Earth. Members of the Filk (folk music with Sci-Fi themes) community have fleshed it out and it has actually been recorded by real musicians like Paul Winter.
