Given the following context:  Bowie moved to the US in 1974, initially staying in New York City before settling in Los Angeles. Diamond Dogs (1974), parts of which found him heading towards soul and funk, was the product of two distinct ideas: a musical based on a wild future in a post-apocalyptic city, and setting George Orwell's 1984 to music.

Bowie said the photographer caught him in mid-wave. He later blamed his pro-fascism comments and his behaviour during the period on his addictions and the character of the Thin White Duke. "I was out of my mind, totally crazed. The main thing I was functioning on was mythology ... that whole thing about Hitler and Rightism ... I'd discovered King Arthur".
