A good whistle is sometimes so underrated! This is one of those songs I play when I've had a really crap day, it brings a smile to my face every time. The simplicity, melody and vocals are brilliant.
And this is strong why?
Guy at the beginning: "Fuck it." plays a cello like a guitar!!! The singer has an awesome "I just slammed a bottle of Jack while chain smoking 50 cigarettes" rasp going on!!
