- Late Cretaceous (Wikipedia)
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after creta, the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period.

“Another Brick in the Wall” is a three-part composition on Pink Floyd’s 1979 rock opera The Wall, written by bassist Roger Waters. “Part 2”, a protest song against corporal punishment, and rigid and abusive schooling, features a children’s choir. At the suggestion of producer Bob Ezrin, Pink Floyd added elements of disco.
