Carefully add the vinegar and lemon and cook to a syrup. Pour over the chicken as it comes off the grill. Allow to rest for 5 minutes before serving. Boil the corn, drain and brush with butter.
Add the roasted chicken wings to the hot sauce glaze and toss to coat. Arrange the wings on a platter, sprinkle with parsley, and serve with blue cheese dressing and lemon wedges.
