Use a can opener to take off the top of the can of beer. Pour out the beer (tip into a glass to drink!) and pour the remaining Jack Daniels into the can, as it will keep the chicken moist while it cooks. Pop the chicken onto the can, legs down, so that it looks like it is sitting upright with the can in its cavity.Stand the chicken and can upright in a baking tray, place in the bottom of the oven and cook for 1 hr, baste with remaining mix and cook for a further 20 mins until the chicken is browned, the meat tender and the juices run clear. If the juices aren’t clear, cook for a further 10 mins, then check again.
