Hey, I have changed the key of this piece a perfect fifth down from where it's
usually written as. It's easier to play and I personally find it easier to sing to...

Verse 1:
Am                   C
All around me are familiar faces.
G                 D
Worn out places.  Worn out faces.
Am                         C
Bright and early for their daily races.
G               D
Going nowhere.  Going nowhere.
Am                          C
And their tears are filling up their glasses.
G               D
No expression.  No expression.
Am                      C
Hide my head; I want to drown my sorrow.
G             D
No tomorrow.  No tomorrow.

Chorus:
Am                  D
And I find it kinda funny.
                Am
I find it kinda sad.
                        D
The dreams in which I'm dying
                       Am
Are the best I've ever had.
                  D
I find it hard to tell you,
                      Am
'Cause I find it hard to take.
                   D
When people run in circles it's a very, very...

Am C   D
   Mad world.
Am C   D
   Mad world
Am C   D
   Mad world.
Am C   D
   Mad world.

Verse 2:
Am                       C
Children waiting for the day they feel good.
G                D
Happy birthday.  Happy birthday.
Am                        C
Made to feel the way that every child should.
G                D
Sit and listen.  Sit and listen.
Am                       C
Went to school and I was very nervous.
G                D
No one knew me.  No one knew me.
Am                     C
Hello, teacher tell me what's my lesson?
G                       D
Look right through me.  Look right through me.

Chorus:
Am                  D
And I find it kinda funny.
                Am
I find it kinda sad.
                        D
The dreams in which I'm dying
                       Am
Are the best I've ever had.
                  D
I find it hard to tell you,
                      Am
'Cause I find it hard to take.
                   D
When people run in circles it's a very, very...


Am C   D
   Mad world.
Am C   D
   Mad world.
Am C   D
   Mad world.
Am C   D
   Mad world. 
(At the end here, on the last 'world' I like to finish on A (major) chord instead
of D, I feel it ends the piece better and sounds more meaningful... but that's just me!)

Well, that's my first tab, hope it works as well for you as it did for me!
