My son-in-law introduced me to this method of cooking a chicken on the grill about 5 years ago.  While his was very tasty and moist, this recipe will put his to shame (yours is still good, Tony!).

1 (3 1/2 to 4 pounds) whole chicken*
1 (12-ounce) can beer (cut off top with a can opener)
1 cup butter or olive oil
2 tablespoons garlic salt or 4 to 5 cloves garlic, crushed
2 tablespoons paprika
Pinch cayenne pepper or to taste
Fresh or dried herbs of your choice
Coarse salt and freshly ground black pepper to taste
