Okay so I was wondering if you guys could help me out with the chords for this song. 
Cause I obviously have no idea what I'm doing...

C, G, Em, D(throughout the whole song except the 
bridge, I dunno what the bridge is.)
C       G           Em                D
Can you tell me how we get there from here?
High in the canyon we can both disappear
Got a change of reason, yeah this much is clear

Can you help me get back, back to the place
Where I was when we got carried away?
Gotta leave this feeling and all I can say

You’re like oxygen; you’re like a midday sun
You’re like a miracle drug in the morning love
That keeps me moving on
You’re like a summer rain, something I just can’t explain
Could it be ---- Or is it really that difficult to say?

Do you remember falling heels over head?
Spent the afternoons just lying in bed
Got a --- and the promise you said

You’re like oxygen; you’re like a midday sun
You’re like a miracle drug in the morning love
That keeps me moving on
You’re like a summer rain, something I just can’t explain
Could it be ---- Or is it really that difficult to say?

And when I start to reel you take the steering wheel.
You give me something that I never knew I was missing
You give me something real.

You’re like oxygen, you’re like a midday sun
You’re like a miracle drug in the morning love
That keeps me moving on
You’re like a summer rain, something I just can’t explain
Could it be ---- Or is it really that difficult to say?

Can you tell me how we get there from here?
