when the first lyrics you hear are: "i heard they were taming the shrew i heard the shrew was you you might as well say fuck because i'm gonna keep on keep on loving you"then no it's not okay to not know all the lyrics. not anymore.though he may sing clear on all but one little line, it's pretty damn important to know that one line. and though i haven't looked up lyrics in forever ever, i go do it. and knowing he sings "i crawl over fifty yards of broken glass just to hold on your hand" is so comforting because 'i crawth the yard is broken /glass just to hold your hand' was depressing... in the wrong sort of way.
