we used NO backdrop. Our orchestra sets up backstage, and the back wall is painted black. They wore kerchiefs and cowboy hats in the Cowboy Bob scene, but otherwise were seen in the back behind the audience.
i recurved great feedback- the audience loved seeing them perform when cast was not in the stage, and the black background made for a start contrast to the bright 80's colors of the costumes, especially the prom scene. I tried to attach a photo- let's see if I did it correctly...Have so much fun with it!
