Playing around one day, figured out some chords that worked pretty well and are 
easy to follow, I love you Cher :) Im a brat :P

Capo: 4th Fret

intro: C, Em, Am, G.

    C 
Yo, my best friend, best friend til the very end
  Em
 Cause best friends, best friends don't have to pretend
  Am
 You need a hand, and I'm right there right beside you
  F               G
 You in the dark, I'll be the bright light to guide you
  C   
 'Member the times, times, times sneaking out the house
  Em
 All of the times, times, times that you had the doubts
 Am
 And don't forget all the trouble we got into
 G
 We got something you can't undo, do
 
C
Laughing so damn hard
 Em
 Crashed your dad's new car
 Am                      F
 All the scars we share 
 G
 I promise, I swear
 
Chorus:
C                    
Wherever you go, just always remember
 Em
 That you got a home for now and forever
 Am
 And if you get low, just call me whenever
 F          G
 This is my oath to you
 C 
 Wherever you go, just always remember
 Em
 You're never alone, we're birds of a feather\
 Am
 And we'll never change, no matter the weather
 F          G
 This is my oath to you

(repeat the chords :) 
 
I know I drive you crazy, mm, sometimes
 I know I called you lazy, and that's most times
 But you complete me, and that's no lie
 You are my tuxedo, and I'm your bow tie
 We in the car, sing, sing, singing our song
 Rocking the building, tear it down, like we king kong
 And in my eyes, you can't do, do no wrong
 You got the best friends sing, sing along
 
Laughing so damn hard
 Crashed your dad's new car
 All the scars we share
 I promise, I swear
 
Wherever you go, just always remember
 That you got a home for now and forever
 And if you get low, just call me whenever
 This is my oath to you
 Wherever you go, just always remember
 You're never alone, we're birds of a feather
 And we'll never change, no matter the weather
 This is my oath to you
 
I'll never let you go
 Woah, this is my oath to you
 Just thought that you should know
 Woah, this is my oath to you
 
Yeah...
 
Wherever you go, just always remember
 That you got a home for now and forever
 And if you get low, just call me whenever
 This is my oath to you
 Wherever you go, just always remember
 You're never alone, we're birds of a feather
 And we'll never change, no matter the weather
 This is my oath to you
 
Oh Ohh
 You should know, you should know, you should know
 Yeah Ohh
 Woah, this is my oath to you
 You're never alone, we're birds of a feather
 Woah, this is my oath to you
