There are four posts for the chords to this song and they're all wrong. The second chord in the chorus is F#m not A. So the chorus is D - F#m - Bm - G. I find this happening all the time because tab posters aren't often singers. If you try and sing the sweet minor melody in this song with an A instead of an F#m it sounds awful. It's hard to imagine how people can get a major and a minor chord mixed up. They are completely different.
