Hi there. I know it can sound maybe strange, but remember that it's a guitar in 
your hands, not a computer.
Why drop C? Maybe it was my guitar but i found my strings got a better sound on 
this song with that tuning.

Here is the intro. Fade in.
D|-----------------------------|
A|-----------------------------|
F|-8-8-8-8-8----13-13-13-13-13-|
C|-6-6-6-6-6----11-11-11-11-11-|
G|-----------------------------|
C|-----------------------------|

Then this part fade in too.
D|-----------------------------------------------------------------|
A|-----------------------------------------------------------------|
F|-8-8-8-8-8-8-8--5-5-5-5-5-5-5--13-13-13-13-13-13-13--6-6-6-9-9-9-|
C|-6-6-6-6-6-6-6--6-6-6-6-6-6-6--11-11-11-11-11-11-11--7-7-7-7-7-7-|
G|-----------------------------------------------------------------|
C|-----------------------------------------------------------------|

And then comes a variation.
D|---------------------------------------------------|
A|---------------------------------------------------|
F|-8-8-8-8-8--5-5-5-5-5--13-13-13-13-13--6-6-6-9-9-9-|
C|-6-6-6-6-6--6-6-6-6-6--11-11-11-11-11--7-7-7-7-7-7-|
G|---------------------------------------------------|
C|---------------------------------------------------|

Let's go!
D|-----------------------------------------------------------------|
A|-----------------------------------------------------------------|
F|-8-8-8-8-8-8-8--5-5-5-5-5-5-5--13-13-13-13-13-13-13--6-6-6-9-9-9-|
C|-6-6-6-6-6-6-6--6-6-6-6-6-6-6--11-11-11-11-11-11-11--7-7-7-7-7-7-|
G|-----------------------------------------------------------------|
C|-----------------------------------------------------------------|

Sometimes there is this.
D|----------------------------------------------------------------|
A|----------------------------------------------------------------|
F|-8-8-8-8-8-8-8--5-5-5-5-5-5-5--13-13-13-13-13-13-13-13-13-13-13-|
C|-6-6-6-6-6-6-6--6-6-6-6-6-6-6--11-11-11-11-11-11-11-11-11-11-13-|
G|----------------------------------------------------------------|
C|----------------------------------------------------------------|

Before the end you can play something like this.
D|--------------------------|
A|--------------------------|
F|-/8-/8-/8-/8--/9-/9-/9-/9-|
C|-/6-/6-/6-/6--/7-/7-/7-/7-|
G|--------------------------|
C|--------------------------|

Then you can buy new pants.
