Open beer and pour off 1/4 (or just drink it). Put in the garlic, rosemary and basil. Put can on top of an oven proof pan or I like to use an aluminum pie plate. Rinse off chicken, remove giblets, etc. Pat dry. Rub with oil and season with salt, pepper or poultry rub. Slip bay leaves under skin on breast. Oil the can. Gently but firmly 'seat' the chicken on the beer can; chicken should be sitting upright with no support. Put chicken on grill and cook for about an hour or until meat thermometer says done (or until juices run clear and skin is translucent). Yummy,.
