This is obviously just the same riff moved down to different positions.
This is the main riff of the song.

In fact most of the song is just this riff played at the three different
positions (G,C,D)

The only different bit is  :

G            Bm          C               D7
I'm   so    glad  that  she's my little girl

G            Bm          C                D7
She's  so   glad  she's telling all the world
