1. "A generation which ignores history has no past...and no future." Robert Heinlein.
2. Greasy Grass? Why you must mean that Battle of the Little Big Horn! June 25, 1876 (Which is the day the movie "She Wore a Yellow Ribbon" is supposed to start.)
3. I wanted Wings. I had not heard the song before, but I recognized the voice of the artist. A LONG time ago, I played some of his songs when I worked as a radio announcer for my college!
