Little riff bit (main notes only):
|-------0-----------0----------|
|---1-3------1--1-3--------1---|
|--------0-2---------0-2-------|
|------------------------2-----|
|------------------------------|
|------------------------------|
Or you can play the chords like this:
|---0-0-0--0--0--0-0--0--0--0--|
|---1-3-1--1--1--1-1--1--1--1--|
|---0-0-0--2--0--0-0--0--2--0--|
|---2-0-2--3--2--2-0--2--3--2--|
|---3-2-3--3--3--3-2--3--3--3--|
|-----3------------3-----------|
Which are basically C, G and F and so I shall label them as such!

F C G
She yawns,
       F (133211@1) C (x32010@1)  GAnd (320003@1)he yawns as well.
   G (320003@1)

    C (x32010@1)                     F (133211@1)        G (320003@1)          CThe (x32010@1)girl that he slept with sleeps too soon at night.
         G (320003@1)                 
When she yawns she tells the truth,
         C (x32010@1)                      F (133211@1)          G (320003@1)       CThat (x32010@1)the boy she adores is just a man she's contracted to.

GC  FG CG C (x32010@1)FG C (x32010@1)I don't think it's quite right- I think I have the right chords, but some might 
not be in the right place, it's quite hard to hear, but it sounds OK to me. Any 
corrections, lemme know!
