This is tabbed from the live version played in TKOL From the Basement

from Start until 0:16 or so, Listen to Thom's guitar to come in then change to

G|-----------------------------------------------------------------------|
D|---------------14---12---------------14---12---------------------------|
A|-----------------------------------------------------------------------|
D|------0-----------------------0----------------------------------------|

Listen to Thom's guitar to come in then changes to:

G|----------------------------------------------------------------------------|
D|---------------12--h14--12-------------12--h14--12--------------------------|
A|----------------------------------------------------------------------------|
D|------0---------------------------0-----------------------------------------|

Pause a couple bars as soon as Thom's vocal first comes in, you can play improv like this:

G|----------------------------------------------------------|
D|------------12-12-----------------12-12-------------------|
A|----------------------------------------------------------|
D|------0-------------0---------0-------------0-------------|
Then back to

G|---------------------------------------------------------------------|
D|---------------12--h14--12-------------12--h14--12-------------------|
A|---------------------------------------------------------------------|
D|------0---------------------------0----------------------------------|

As soon as chorus comes play these in whichever octave you want, I added a couple extra 
notes and slides here and there:

G|------------------------------------------------------|
D|------------------------------------------------------|
A|------------------------------------------------------|
D|--0-0----8-8----10-10----10-10-12---------------------| play that 3 times

ends with:


G|--------------------------------------------------|
D|--------------------------------------------------|
A|--------------------------------------------------|
D|--8-8----8-8----10-10----12--14--12---------------|

Play those in the higher octave on the high D string is you want.


Soon as vocals end with "OhOh OhOh OhOh Ohhhooooohhh" back to

G|---------------------------------------------------------------------|
D|---------------12--h14--12-------------12--h14--12-------------------|
A|---------------------------------------------------------------------|
D|------0---------------------------0----------------------------------|

I think you can figure it out from here, rinse and repeat.

Around 3:30 the bass goes back to the beginning rifs until the songs ends:

G|---------------------------------------------------------------|
D|---------------14---12---------------14---12-------------------|
A|---------------------------------------------------------------|
D|------0-----------------------0--------------------------------|

Some variations for this part: (Colin's been playing these for the live shows since RH 
appeared on the Colbert report):

G|---------------------------------------------------------------|
D|---------------14---12---------------12---10-------------------|
A|---------------------------------------------------------------|
D|------0-----------------------0--------------------------------|


G|---------------------------------------------------------------|
D|---------------14---12---------------10---12-------------------|
A|---------------------------------------------------------------|
D|------0-----------------------0--------------------------------|

That's it enjoy.
