Checking for Here Come the Warm Jets release date, I ended up on this page which discusses the discrepancy between the vinyl and label information, and concludes it was because of the oil crisis: https://forums.stevehoffman.tv/threads/brian-eno-here-come-the-warm-jets-what-was-the-original-release-date.755536/. So, recorded in September, scheduled for November and that's what the first UK pressing says, but apparently no-one heard it before early 1974.
