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
The solo is over the G/C/D riff.
