This sounds best if you fingerpick through it. If you're not used to fingerpicking, this
is a good song to practice with. The G-A-C chord progression at the beginning of each
verse/chorus is optional; it just adds to the song a bit. You don't have to play the 
full chord with each of those, just the root note.
You can also play C-B-Am when transitioning to the Am on the third line of every
verse/chorus. It sounds like he does that in the recording.

(Verse 1)
G      A   C
There are loved ones in the glory
           F               C
Whose dear forms you often miss
                           Am
When you close your earthly story
          C        G        C
Will you join them in their bliss?

(Chorus)
G     A   C
Will the Circle be unbroken
       F
By and by, by and by
C                Am
Is a better home awaiting
        C    G     C
In the sky, in the sky

(Verse 2)
G   A    C
In the joyous days of childhood
         F                C
Oft they told of wondrous love
                     Am
Pointed to the dying saviour,
          C          G   C
Now they dwell with him above,

(Chorus)
 G     A   C
Will the Circle be unbroken
       F          C
By and by, by and by
                  Am
Is a better home awaiting
        C    G     C
In the sky, in the sky

(Verse 3)
G   A    C
You remember songs of Heaven
          F                   C
Which you sing with childish voice
                           Am
Do you love the hymns they taught you
       C        G          C
Or are songs of Earth your choice


(Chorus)
G     A   C
Will the Circle be unbroken
       F          C
By and by, by and by
                Am
Is a better home awaiting
         C   G     C
In the sky, in the sky


(Verse 4)
G   A   C
You can picture happy gatherings
           F             C
'Round the fireside long ago
                         Am
And you think of tearful partings
          C        G    C
when they left you here below


(Chorus)
G     A   C
Will the Circle be unbroken
       F           C
By and by, by and by
                Am
Is a better home awaiting

In the sky, in the sky


(Verse 5)
G   A  C
One by one their seeds were emptied
           F             C
And one by one they went away
                  Am
Now the family is parted
        C      G        C
Will it be complete one day?

(Chorus)
G     A   C
Will the Circle be unbroken
       F          C
By and by, by and by
                 Am
Is a better home awaiting
        C    G     C
In the sky, in the sky
