I transcribed this from the Live in Paris video on Youtube: 

You'll need a capo on the first fret to play in the same key as Julia.
 
[Intro]
G  C  Em
G  C  Em

[Verse 1]
    G           C        Em
How long must I wait for you?
    G           C        Em 
How long must I wait for you?
    G               C    Em
How long 'til this fire grows?
G          C       Em 
Do we ever really know? 

[Verse 2]
    G           C        Em
How long must I wait for you?
    G           C        Em
How long must I wait for you?
    G               C    Em
How long 'till this fire burns?
G           C      Em
When will I get my turn?

[Chorus]
Am       Em      G
And the cruelest part
Am             Em            G
I will wait forever for your heart
Am       Em           G
And it's sad but it's true
Am             C        G
I will wait forever for you

[Verse 3]
        G           C            Em
Oh, How long must I eat this old bread?
   G         C            Em
No sweets anymore, no cigarettes
    G           C              Em
No joy from the things I once adored, no darling
     G              C      Em
They don't bring me joy anymore

[Chorus/Outro]
Am       Em      G
And the cruelest part
Am             Em            G
I will wait forever for your heart
Am       Em           G
And it's sad but it's true
Am              Em      G
I will wait forever for you
    Am             Em       G
Oh, I will wait forever for you
Am             C        G
I will wait forever for you...
