OK so this is what i've been able to figure out, the entire song is the same
chords just a variation in what order they're in.

Standard Tuning


e-----------------------------------------------------------------------------||
B-----------------------------------------------------------------------------||
G----------------------------------------------------------------------------.||
D--7-7-7-7-7-7-7-7-8-8>6-6-6-6-6-6-6-6>8-8-----------------------------------.||
A--7-7-7-7-7-7-7-7-8-8>6-6-6-6-6-6-6-6>8-8------------------------------------||
E--5-5-5-5-5-5-5-5-6-6>4-4-4-4-4-4-4-4>6-6------------------------------------||

This next part is done with bells but it can be done on guitar as well.

e-2-2-2-2h4-2-2-2-2h4------------------------------||
B---------------------5-5-5-5h7-4-4-5-5------------||
G-------------------------------------------------.||
