Saw the chorded version of this & made it better & took away the capo for those of 
you who haven't gotten around to buying one yet.
& I know it's supposed to be played in Drop Db & all that, but this is to make 
things a bit easier for people.
Now, I'd play this in all 5th chords [or lazy barre chords] because it sounds better that way.

Intro.

Repeat this pattern for the first verse to mimick the piano sound, improvise

Verse 1:
Bbm (x13321@1)                                
Took a bite out of a mountain range,
F#thought (244322@1)my teeth'd break, the mountain did.
Bbm (x13321@1)

Verse 2: [Same as First Verse]

I wrote a note to the jungle and
They wrote me back that I was never crowned,
King of the jungle so,
There's an end to my horizon.

I took a ride, I took a ride,
I wouldn't go there without you.
Let's take a ride, we'll take a ride,
I wouldn't leave here without you.
