Hornets In The Elevator
Titles aren't meant to be too literal-minded and are open to broad interpretation (insofar as titles ever bear any relation to the instrumentals named).
But the elevator I've in mind is a grain elevator. A sort of enclosed conveyor belt draws the grain way up only to let it slide down one chute or other to a truck or storage bin.
Taken as a figure of speech, hornets in said gizmo might be like bats in the belfry. Or worse.
