If you start to moan about the nights you attend,give it a break. Recharge your batteries. Its a tough call when to introduce an "unknown" into a set.A fine line between right an wrong - too many unknowns may not work for some while others can't get enough "new" stuff. Like Len has just pointed out,some tunes are lurking in the boxes,not neccesarly big ticket or unknown,but tunes to freshen up a set.
