I still think the desired effect comes from retarding the tempo. It's the difference between playing for dancers and performing an artistic interpretation for an audience in a theater. I don't care who printed out the sheet music - it's bound to be wrong, or interpreted differently. If you listen closely, and subdevide the beats in time .... it all fits in logical manner. You don't even need drums in a song like that - the melody and harmony can carry it quite well. A truly great song can stand alone with no gingerbread.
