Earth, Wind & Fire performing live!
Doug (Henning) created fantastic illusions. He devised an opening where we would arrive onstage from tubes hanging a hundred feet high above the stage. The tubes lowered to the stage, and we gradually became visible to the audience inside the cylinders. Then the tubes rose back to high above the stage, and we proceeded with the show. The tubes had to land within a quarter of an inch of accuracy every night. And since they were coming from a hundred feet in the air, our riggers had to have everything precise. It was our best show opening.
