In the original Les Miserables, after all of the students are killed on the barricade the orchestra starts a very slow, quiet rendition of 'Bring Him Home.' Javert and the other police appear, combing the dead bodies for Jean Valjean. While they're searching, the turntable/barricade rotates and we see the other side, the spotlight on the dead bodies of Enjolras and Gavroche as the song reaches a crescendo.
The turntable rotates again, and now we see Javert sitting alone on the deserted barricade, staring glumly at the ground as he tries to figure out how Valjean got away. At length he spots the grate in the floor (entrance into the sewers) and goes down into it, which leads into the scene in the sewers and "Dog Eat Dog."
I always loved that set of transitions for its sheer cinema-like movement, and the power of those images. It's not the same now, without the turntable. Not at all.
