Apollo 11 makes me think of Hope Eyrie.
Hope Eyrie is a lovely commemoration of the Apollo landing. It’s probably the best known and most celebrated filk song.
I love the lyrics, especially the chorus:
“But the Eagle has landed; tell your children when.
Time won’t drive us down to dust again.”
This video (a tad cheesy in places) is captioned with the lyrics:
Each of these videos features the music of Hope Eyrie, written by Leslie Fish & performed by Julia Ecklar. Thanks to the generosity of Prometheus Music, you can download an mp3 from http://www.totouchthestars.com (a fun space-related album from a great filk label).
