This is the only useful info I could find on the net for playing this song.

Despite showing guitar chords it's not so simply transferred to a guitar only
arrangement.
Below is my attempt.
If you can read music, get the rough timing from the above link, otherwise just
listen to the song.
Below is my attempt.
Capo 6 - Std Tuning
Sequence A
Bmaj9 | Bmaj9+D# | Bmaj9 | pick the 'da-de-da'
[ Tab from: http://www.guitaretab.com/j/john-legend/366214.html ]
e|----0-------0----------0------3--5--3---|
B|----1-------1----------1----------------|
G|----0-------2----------0----------------| Repeat this section twice to make 2 bars.
D|----2-------2----------2----------------|

E|----1-------1----------1----------------|
Sequence B
F#add9/A# | F#/A# | F#add9/A# | F#/A#
e|----0-------0--------0----------0--|
B|----3-------1--------3----------1--|
G|----0-------0--------0----------0--| This section is already 2 bars long.
D|----2-------2--------2----------2--|
A|----3-------3--------3----------3--|
E|----0-------0--------0----------0--|
2 beats | 2 beats | 2 beats | 2 beats
Whole song literally goes Seq A, Seq B, Seq A, Seq B, etc
Let me know if you figure our how to do the whistle solo :P
