Show the degrees above the chords — relative to G or to Em; comparing both readings is a practice of its own.
Every chord of the key, listed 1 to 7 separately for each key. Chords played in the song show how often they appear; chords from outside the scale sit next to their own degree.

The key pair is G major and its relative E minor (1 sharp). 5 different chords appear 103 times in total; 5 of them sit naturally inside the shared scale. Everything stays inside one scale, which is why the song is easy to follow by ear.
The move to watch is C → G, heard 16 times. From the G side it reads IV → I (plagal cadence: the soft 'amen' ending); from the Em side it is VI → III. Knowing where these arrivals fall helps you feel the phrasing and anticipate the next chord.
Empty slices are chords the song doesn't use.
The song is already written in its easiest key for guitar.
The opening C lays a solid floor for everything that follows. The chords that keep coming back are C, D, Em, G; read them as IV–V–vi–I in G or VI–VII–i–III in Em. No chord leaves the shared scale, so a single pentatonic shape works over the whole song. Keep an ear on C → G (IV → I in G, VI → III in Em): plagal cadence — the soft 'amen' ending. Ending on G, the song seals G as home.
This analysis is generated from the song's chords by akorculuk's harmony engine using consistent rules. When you change key, the degrees stay the same; only the chord names change.
