Yes you are right Billy,about the smoking thing,but for us none smokers its better we dont stink of smoke in the morning,and Iam not coughing up in a morning after a allnighter as well.
On Over kill, I can only speak about allnigters,If there is a big nighter like say Stoke, that affects the other nighters attendance either side of the date of Stoke ive noticed.
