Songs that were written in response to, or about, other songs

T-Rex - "Children of the Revolution", "Born to Boogie"
David Bowie - "Lady Stardust" (originally titled "Song for Marc"), "Star Man"

"Children of the Revolution" was a song they were working on at the time so it seems like this is Bowie giving a shout out to his friend's new single. "Starman" I always felt was about "Get It On" and T-Rex blowing up. "Born to boogie" was the movie/live show they were making with Ringo at the time, for sure he knew about it. thus "Let all the children boogie"

Robyn Hitchcock - Listening to the Higsons
