    A                       E7           F#m

There are countless variations on this theme throughout the song, so you can stick to 
chord shapes shown or make up your own variations.

Chord pattern example: verse 1:
I?ve got the key to the highway
A                     E7
    Be allowed that I do go
F#m
Gonna leave here runnin?
      A
   Walkin?s most too slow
E                    A (turnaround)

Here?s a simple turnaround idea, which can be expanded upon if you like, although you 
have to include a turnaround at all.

e|-----------------|
B|--5-3-2-1--------|
G|-----------------|
D|-----------------|
A|-7-5-4-3-2-0-1-2-|
E|-----------------|

Here?s an example of a fill that?s sometimes used when changing from A to E:

A|---2-0-----|
E|-0-----3-0-|

Verse 2 lead ? King sings
In this verse there is hardly any lead guitar at all. For most of the verse the only 
guitar to be heard is this:
B|-10
G|-11

there is a bit of lead:

e|------------------7/9----------|
B|-13-12-12-10-10----------------|
G|----------------9-----9-9-9?-9-|
D|-----------------------------9-|
A|-------------------------------|
