Hi!
Good song.
It's very hard to hear the chords but it sounds like it's played in E minor. The second time you sing 'don't you see me and see me' at about 2.52 you sing what sounds like Eb over a C chord. One might say you sing the note E a bit flat, but it sounded really good when I substituted the C major chord to a C minor. Try!
Cheers,
Martin
