in response to BlueWizard, i think the lyricist may have been trying to pull a beatles lyric. if you've ever heard "all you need is love" john sings "There’s nothing you can do that can’t be done. Nothing you can sing that can’t be sung.
Nothing you can say but you can learn how to play the game.
It’s easy. Nothing you can make that can’t be made.
No one you can save that can’t be saved.
Nothing you can do but you can learn how to be you in time.
It’s easy." basically meaning if you can do something (you fill in the blank) it's already been done or somebody already knows how to do it. Just a little info cause that lyric just struck a chord with me! and i freaking love the beatles
"I hear America singing...the checker, the trucker, the worker, the housewife..." WORKING
