This should do it:
Intro + Verse: (~ means a quarter tone bend, listen to the song!)
|-----------------------|--------------------1~---|
|-------------------1-3-|----------------1-3----3-|
|---2--------0-2--2-----|---2--------0-2----------|
|-0---0-3~-0------------|-0---0-3~-0--------------|
|-----------------------|-------------------------|
|-----------------------|-------------------------|
alternatively play it on upper frets, so the bridge becomes easier:
|-----------------------|-------------------------|
|-----------------------|--------------------6~---|
|-------------------5-7-|----------------5-7----7-|
|---7--------5-7--7-----|---7--------5-7----------|
|-5---5-8~-5------------|-5---5-8~-5--------------|
|-----------------------|-------------------------|
chord, that's being held:
[ Tab from: https://www.guitartabs.cc/tabs/p/portugal_the_man/children_tab.html ]
|---| |---|
|-3-| |---|
|-2-| or |-7-|
|-0-| |-7-|
|---| |-5-|
|---| |---|
bridge (if you want to call it that way ; ) )
|---------------------------|
|---------------------------|
|---------------------------|
|-5-7-x-10-7----------------|
|-3-5-x--8-5--5-5-5-5-3-3-3-|
|-------------3-3-3-3-1-1-1-|
chorus: (tell your children...)
|-------------------------------------------------------------------|
|-------------------------------------------------------------------|
|-------------------------------------------------------------------|
|-5/7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7---------------------------------|
|-3/5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-3-3-3-3-7-7-7-7-|
|-----------------------------------3-3-3-3-3-3-3-3-1-1-1-1-5-5-5-5-|
and that's it, regarding the "rhythm guitar", maybe later I will add the leadstuff...
it : )
