I figured this was how to do it just by playin it by ear.
You need to figure it out the way it is most comfortable, not the exact way
 they play it.
You can modify where needed, but this is what works for me.

The intro can be seen on other posts.
I just wanted to post the bridge.

1st measure

E-----------------------------------------------------------------
A-----------------------------------------------------------------
D-(18)(18)(18)(18)--------------------------------(18)(18)----(18)
G-----------------(16)(16)(16)(18)(18)(18)(16)(16)--------(16)----

2nd measure

E-----------------------------------------------------------------
A-(14)(14)(14)(14)------------------------------------------------
D-----------------(18)(18)(18)(16)(16)(16)----------------(18)(18)
G-----------------------------------------(18)(18)(16)(16)--------

3rd measure

E-----------------------------------------------------------------
A-----------------------------------------------------------------
D-(14)(14)(14)(14)------------------------------------------------
G-----------------(13)(13)(13)(16)(16)(16)(13)(13)(16)(16)(13)(13)

4th measure

E-----------------------------------------------------------------
A-(16)(16)(16)(16)------------------------------------------------
D-----------------(18)(18)(18)----------------------------(16)(16)
G-----------------------------(20)(20)(20)(18)(18)(16)(16)--------

Repeat until you drop the octave then play this line

1st measure (lower octave)

E----------------------------------
A----------------------------------
D--6-6-6-6-9-9-9-------9-9-6-6-9-6-
G----------------6-6-6-------------

2nd measure (lower octave)

E--7-7-7-7-------------------------
A----------------9-9-9-------------
D----------6-6-6-----------9-9-6-6-
G----------------------6-6---------

3rd measure (lower octave)

E----------------------------------
A--7-7-7-7-------------------------
D----------6-6-6-9-9-9-6-6-9-9-6-6-
G----------------------------------

4th measure (lower octave)

E--9-9-9-9-------------------------
A------------------------------9-9-
D----------6-6-6-----------9-9-----
G----------------8-8-8-6-6---------

The second time thru the lower octave you will notice they go back into the
song after the 2nd measure, so don't forget to transition back to where you
usually play the song.
Hope this helped and to Randall, God Bless and I hope you had a good time at 
the Winter Retreat.
