Birdy - Words As Weapons Chords & Tabs

Hey, I watched the MahoganySessions video of Words As Weapons and the only other tab was 
completely wrong, not what they play.
So I tried to copy what her guitarist plays and this is what I got.

E|---------------------------|
A|-3------3------3------3-2--|
D|---2-2----2-2----2-2-------|
g|---------------------------|
b|--3-3-3--3-3-3--3-3-3--3-3-|
e|---------------------------|
[ Tab from: https://www.guitartabs.cc/tabs/b/birdy/words_as_weapons_tab.html ]
E|---------------------------|
A|-5------5------5------5-4--|
D|---4-4----4-4----4-4-------|
g|---------------------------|
b|--5-5-5--5-5-5--5-5-5--5-5-|
e|---------------------------|

So these two parts are played through the whole song, play the first and slide to the 
second and back again.
I cant figure out the very first intro part, where he plays on the 5th fret, suggestions?
Thanks for trying =]
