Melt the butter and seafood seasoning in a small saucepan over medium heat. Brush the baguette slices on both sides with 1 tablespoon of the butter mixture and place on a baking sheet. Brush the corn with 1 tablespoon of the melted butter and add to the baking sheet. Brush the kielbasa with 1 tablespoon butter and add to the same pan. Toss the shrimp with 2 tablespoons butter mixture then transfer to the pan. Reserve the remaining melted butter mixture.
Cut three 22-inch long pieces of heavy-duty foil. Put two sheets on a work surface, one on top of the other so they form a cross. Place the potatoes in a 10-by-10-inch square in the center of the foil. Scatter the onions and clams over the potatoes and season with 1/2 teaspoon salt and a few grinds of black pepper.
Fold all four sides of the foil up towards the center to create a bowl, but do not seal it. Add the wine, lemon juice, garlic and the remaining 3 tablespoons of the melted butter mixture. Tightly seal the foil packet so no liquid can escape. Wrap the packet with the remaining piece of foil to make sure it is secure.
Place the foil packet, corn and kielbasa on the grill and cook, flipping the corn and kielbasa as needed (do not flip the foil packet) until the corn is tender and charred in spots, the kielbasa is charred and heated through and the potatoes in the foil packet are tender and the clams have opened up, about 20 minutes. Remove the corn and sausage from the grill to a clean cutting board as they are ready. With 5 minutes of cooking time left, add the shrimp to the grill and cook, flipping once, until bright orange on the outside and white and opaque at the center, about 5 minutes. Grill the bread slices, flipping once, until toasted and charred on both sides, about 1 minute.
Cut each ear of corn into 4 pieces and slice the kielbasa on a deep bias. Divide the shrimp, corn and kielbasa between 4 shallow bowls. Open the foil pack (watch out for hot steam) and divide the potatoes and clams between the bowls (discard any clams that do not open). Spoon some sauce into each bowl. Sprinkle with chives and Old Bay seasoning. Serve with a lemon wedge and grilled bread on the side.
