I was wondering why nobody posted the tabs, Maybe they are too obvious ;)
Never-mind, I posted the lyrics so you can see exactly when you should play (although 
it's so simple you can play it while sleeping)

Tuning Standard

Intro:
|-----5------5-----------|
|------------------------|
|-5-------5--------------|
|------------------------|


|-----5--------------5----------------------------------------5---------------|
|---------------------------------5--------------5--------------------------5-|
|-5-------------5----------------------------------------5--------------------|
|----------------------------3-------------3---------------------------5------|
Goodbye cruel world    I'm leaving you today        Goodbye,      Goodbye,


|-----------5--|
|--------------|
|------5-------|
|--------------|
  Goodbye

(interlude) Play 2 Times

|-----5------5-----------|
|------------------------|
|-5-------5--------------|
|------------------------|

And then Play the whole (except the intro) again and end on :

|--------|
|--------|
|------5-|
|--------|

Hope you enjoy :)
