Back in 1946 The Ray Bradburry story "The Green Hills of Earth" Was done as a Radio Program and Oscar Brand sang a song or wrote the song for the show to the tune of Acres of clams I only remember the last line of the chorus as "I pray for one last landing on the Green hills of earth" Actually the words were in the story as a poem and Oscar just put them to the music. You could probably find the story in an anthology of Bradburrys works
