Heat a grill with a lid big enough to accommodate the bird.  Put a drip pan below the grates.  Mix the ingredients for the Spice Rub until they are well blended. (this will keep, covered, i in the refrigerator for 1 week).  Rub it all over the chicken inside and out.  Open the beer and take a big swig and add the remaining spice mix.  Set the chicken on the beer can so the legs are at the bottom and the wings are at the top.  Stand the beer can on the grate over the drip pan.  Put the cover on and cook over indirect heat until the juices run clear about 1 hour.  Chicken can also be cooked in a 350-degree oven.
