The chords that were already on here are right 
for the most part, but it was missing the 
intro/solo/whatever you want to call it. 
It's simply this:

e|----------------------|-------------3---1----|
B|----3---3-3---3---3-3-|---3---3-3---------3--|
G|----------------------|-----------0---0------|
D|--0---0-----2---2-----|-3---3----------------|
A|----------------------|----------------------|
E|----------------------|----------------------|
(Hold the '3' on the 'B' string throughout)

Play the whole thing three times, then play just 
the first half, following it by strumming the 'G' 
chord. Then play the chords already provided in 
the other tab on here.
