[Intro]
G

[Verse 1]
        G
May the good Lord be with you
     C                  G
Down every road you roam
And may sunshine and happiness
C                                  G
Surround you when you're far from home
And may you grow to be proud
C                 G
Dignified and true
And do unto others
    C                    G
As you'd have done to you


[Chorus]
    A                   C*
Be courageous and be brave
            Em                  C*
And in my heart, you'll always stay
            G    C          G
Forever young, forever young


[Verse 2]

         G
May good fortune be with you
     C                         G
May your guiding light be strong

Build a stairway to Heaven
       C                 G
With a prince or a vagabond


[Chorus] (Extended)
            A                C*
And may you never love in vain
           Em                 C*
And in my heart you will remain
            G  C            G
Forever young, forever young
A   C*    G    A   C*    G
Forever young, forever young


[Verse 3]
         G
When you finally fly away
        C                        G
I'll be hoping that I served you well

For all the wisdom of a lifetime
C                 G
No one can ever tell


[Chorus] (Extended)
      A                    C*
But whatever road you choose
            Em                   C*
I'm right behind you, win or lose
            G  C            G
Forever young, forever young
A   C*      G   A   C*    G
Forever young, forever young
A  C*    G
Forever young
