If you only need the chord Don try this lot :-

         C         Em             Am                   C
When the stars all glitter and the streets are dim and dead
       Dm                  G                  
And all decent people are a sleeping in their bed
            C                  Em       Am            C
With their prayers and their 'Goodnight,Sleep well' s said
       Dm                     G
And the moon's up and in full sail
          Dm                         Em               Am
There's a banging in the alley and a whistling on the breeze
F                            G
A churning and a burning and a turning of the wheels
    C          Em          Am               C
They all roll over in their bed and think of me
         Dm                G    C
When I'm working on the Midnight Mail
C                        Am   Dm                      Am
Working on the Midnight Mail Working on the Midnight Mail
      C                            Am   
In my boots with my shovel and my pail
         Dm            G         C
I'll go working on the Midnight Mail
