So I really enjoied this song in the musical, and I couldn't have been the only one, so 
tabbed it out.

Here are some of the more unfamiliar chord shapes

  Dadd4    Em7     Eb7     Dm7     Bm7
|---0---|-------|-------|-------|-------|
|---3---|---8---|---8---|---6---|---3---|
|---0---|---7---|---6---|---5---|---2---|
|---4---|---9---|---8---|---7---|---4---|
|---5---|---7---|---6---|---5---|---2---|
|-------|-------|-------|-------|-------|
