There's a Key

So I'm losing my marbles
 One marble at a time, it's true
 When I'm stuck between what we have done
 And what we're gonna do
 There's a key on my piano that I play for you
 And now I'm conquering an ocean
 One wave at a time, it's true
 'Cause I can not beat the devil
 I'm taking on the deep, deep blue
 Armed with this key on my piano that I play for you
 Can you hear it?
 Can you see the continental divide?
 Oceans wide till you jump inside this tidal wave with me
 So i'm losing my marbles
 One marble at a time, it's true
 When I'm stuck between what we have done
 And what we're gonna do (what we're gonna do)
 There's a key on my piano that I play for you
