Just play the chorus to You're the Best Thing About Me.G-D-A-BmNo, seriously. That's pretty much the whole song. Just alternate between that and G-D-A during most of it in various forms. Middle 8 is Em-G-D.
As a novice bassist/guitarist, I knew the song sounded similar to YTBTAM, just couldn't put my finger on exactly how. All makes sense now, though.
