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:
[ Tab from: https://www.guitartabs.cc/tabs/m/material_issue/diane_tab.html ]
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.
