“The song was written because of going to see the film 2001: A Space Odyssey, which I found amazing,” Bowie told Performing Songwriter magazine in 2003. “I was out of my gourd anyway, I was very stoned when I went to see it, several times, and it was really a revelation to me. It got the song flowing.”
“Thematically, I have always dealt with alienation and isolation. I have often put myself in situations where I am isolated so I can write about that,” said Bowie. ‘Space Oddity’, the atmospheric tale of an abandoned astronaut orbiting Earth, remains one of the most quirky and poignant songs of the late 60's. This masterpiece has continued to influence society into the 21st Century.
I can't think of a better song that paints a picture of a person.
