"The song Chicago 1945, on the other hand, makes a number of significant Chicago-related citations. The World's Fair (which visited Chicago), The Chicago Tribune (local newspaper), Al Capone (of The Chicago Outfit fame), and so on. While making these citations it tells the story of a mysterious disappearance in the area. "Three girls disappeared on a cold windy night, never to be found again, never to be found again!" sings Jackson in the first verse. Who solved the mystery late Chicago night? Ya can't hide the truth so won't ya turn on the light" he continues in the choruses, before launching into a flurry of high-pitched "hoo-hoo" and "hee-hee" ad libs. The track finishes with Jackson chanting "Chicago! Chicago!" over and over in his trademark, gritty (slightly angry) vocal-style. The track was constantly on Jackson's mind over the course of his career, and was worked on during the Invincible sessions and again at Neverland in 2004."
