This song is pretty fun to play, and isn't very hard.

The main riff is:
e|----------------------------|
B|----------------------------|
G|----------------------------|
D|----------------------------|
A|--0--0--4--4--5--5--6--7----| (x8)
E|----------------------------|

During the main riff another guitar can be heard,
that does variations on the riff, example:
e|----------------------------|
B|----------------------------|
G|----------------------------|
D|--------5--5--4--4--0--2----|
A|--0--0----------------------|
E|----------------------------|
Chorus:

D           B
Cause I'm a freeman...        No need to run in the city of...
e|--------------------------|
B|--------------------------|
G|----------7--7--7--7--4---|
D|----------7--7--7--7--4---|
A|----------5--5--5--5--2---|
E|--------------------------|
  dreams
e|----------------------------------------------------|
B|----------------------------------------------------|
G|----------------------------------------------------|
D|----------------------------------------------------|
A|--0--0--4--4--5--5--6--7--9--9--10--10--12----------|
E|----------------------------------------------------|

Repeat verse & chorus, then:

                    You'll know when I get there
    A        How'm I gonna know...
e|--5--5------------------------------------------------|
B|--5--5------------------------------------------------|
G|--6--6------------------------------------------------|
D|--7--7------------------------------------------------|
A|--7--7------------------------------------------------| (x4)
E|--5--5------------------------------------------------|

Repeat 4 more times much faster ("How'm I gonna, How'm I gonna..")

Solo:

B|------------------------|-------------------------|
G|--7b===(9)---7h5--------|-----5--7b===(9)---------|
D|------------------7--5--|--7----------------------|

D|------------------------|-------------5b(6)~~-----|

Then it breaks down into the funky part:
At first only the bass plays,

G|-------------------------|-------------------------|
D|-------------------------|-------------------------|
A|-------7---------5-----7-|-------7---------5-----7-|
E|-0--0-----5h7h5-----7----|-0--0-----5h7h5-----7----|

On the 5th bar the guitar comes in:
  Oh yeah...
  Wild,       crazy           crazy    &     wild

And here are the lyrics:

(Main riff)
yeah (x8) Well...

Don't need no friends in high places
No Mr. Big on the hill
Gonna do my own dirty work, yeah

'Cause when the shit hits the fan
You better run if you can
Gonna do my own dirty work, yeah

(Chorus)
'Cause I'm a free man
Don't you look at me, man
No need to run in the city of dreams

(Main riff)
Well you can keep your confession
For Mr. Big on the hill
You did your own dirty work, yeah

And when the shit hits the fan
You'd better run if you can
You did your own dirty work, yeah

(Chorus)
'Cause you're a free man
Don't you look at me, man
No need to run in the city of dreams
A A
{How'm I gonna know when I get there? }
{       You'll know when you get there}(x4)
How'm I gonna, How'm I gonna...

(Guitar solo)

(Chorus)
Cause you're a free man
Don't look at me, man
No need to run in the city of dreams

Get down, wild, crazy, crazy, wild...

'Cause I'm a free man
Yes I'm a free man
