Listen to the song to get the timing and all, of course.

Could I possibly be insane 
(Verse riff)
To think you and I have life figured out 
(Verse riff)
And how does one approach this 
(Verse riff)
When all our past loves have let us down 
(verse riff x3)

(Chorus riff played along vocals)
Let's break the walls down and find how to live
(Chorus riff played along vocals) 
'Cause you and I have so much to give

I know that I have taken things 
(Verse riff)
Taken things I've had for granted 
(Verse riff)
But I know this one thing's for sure
(Verse riff) 
I won't let you ever walk out my door
(Verse riff x3)

(Chorus riff played along vocals)
Let's break the walls down and find how to live
(Chorus riff played along vocals) 
'Cause you and I have so much to give

We are forming a sight to behold 
We hold forever and ever
