^{Key: :[F] (w: Johnny Cash)}

INTRO: [Bb] [Eb] [Bb] [F] [C7] [F]

VERSE 1:
I keep a [C7] close watch on this heart of [F] mine
I keep my [C7] eyes wide open all the [F] time
I keep the [Bb] ends out for the tie that [F] binds
Because you're [C7] mine, I walk the [F] line [Bb]

VERSE 2:
I find it [F] very, very easy to be [Bb] true
I find my-[F]-self alone when each day's [Bb] through
Yes, I'll ad-[Eb]-mit that I'm a fool [Bb] for you
Because you're [F] mine, I walk the [Bb] line [Eb]

VERSE 3:
As sure as [Bb] night is dark and day is [Eb] light
I keep you [Bb] on my mind both day and [Eb] night
And happi-[Ab]-ness I've known proves that it's [Eb] right
Because you're [Bb] mine, I walk the [Eb] line [Bb]
