Melt butter in a saute pan over medium heat and cook celery, onion, thyme and garlic until wilted. Toss in shrimp and cook for 3 minutes. Add sausage to the pan, then stock. Place bread cubes in a bowl and pour the shrimp mixture over. Stir to completely moisten the bread, then add the green onions, parsley, and season with salt, pepper, and hot sauce, to taste. Let stuffing cool and then divide into 8 portions. Wrap 1 quail around each portion, using toothpicks to secure the back. Rub each quail with a little butter and season with salt and pepper. Place quail on baking sheet (not too close together) and roast for 12 to 15 minutes until golden brown and firm, but not dry. To serve, place 2 quails on each of 4 dinner plates and spoon sauce over top.
Spicy White Wine Sauce:
Place shallots, white wine, broth, and hot sauce in a small pot and bring to a boil. Cook until reduced to about 3 tablespoons and then whisk in butter, 1 tablespoon at a time. Finish with a squeeze of lemon and a pinch of salt, if necessary. Spoon sauce over quail and serve.
