Art is indeed thinking of "The Green Hills of Earth" by Robert Heinlein. I have seen recordings of the song atributed to his character Rhysling or Reisling, never sure how its spelled unless its right in front of me. Art must remember the X Minus One episode better than the short story. Rhysling played an accordion and was blinded due to a reactor accident. The rest is pretty close. There are also recordings of music from Mark Schultz's "Xenozoic Tales" available at comic shows and through Bud Plants catalog.

For the Filkers there is a Rock and Blues band of comic book professionals called "Seduction of the Innocent". Pretty good from most accounts.
