Those are the chord diagrams for this approach:
G = 320003 C = X320010 D = XX0232 Dsus2 = XX0230
Strumming pattern goes:
G G C C C C G G C C C C
Down,DownUP,UpDownUp-Down,DownUP,upDownup...
Chords are super basic. One instrumental measure follows each verse, so play the G-C-G-C stuff after
"take our time...", "know our mind...", "we won't care...", etc etc.
Listen to the record to get it right.
