Simply put ... a hangover?

@jcaudio Exactly. To use the old expression, "the morning after the night before." On the vinyl release, the first song on the first side of Jethro Tull's LP debut (1968), "This Was." Therefore, the analogue, if you will, to The Doors' "Break on Through (To The Other Side)" or The Grateful Dead's "The Golden Road to Unlimited Devotion."
