Verse.
        G                    C
She's savin' all her money tryin' to get ahead
             G                                D
But all the luck in the world won't keep her baby fed
     G                             C
The boss is on her back and it's gettin her down
        G                                D
she's waitin' for the one she loves to come around.
       G                          C
He's diggin up concrete while everybody sleeps
  G                              D
Fillin' in the cracks in these lonely streets
            G                           C 
she said, "don't you worry honey, it'll be ok, 
       G                             D        D/G
cause one of these days we're gonna fly away"

Chorus
  C                        D              G/Gm7
there's only one Saturday night in every week
,C            D         G               Gm7
Sunday's for recoverin,five days for discoverin',
  Am            C              D     D/G  D
people walkin' down the same street,
                  C                 D              G
you know there's only one Saturday night in every week.

verse
         G               C
He's a bona fide rebel tryin' to get ahead
      G                      D
but real life's got him and now he's gettin bored
     G                    C
he barely makes a livin pickin' up stuff
      G                            D
when all he really wants to do is kick up the dust
     G                    C
she spends all her days talKin on the phone
   G                        D
tryin to sell you somethin you don't wanna own
         G                         C
she's dreamin of a break from the daily grind
         G                      D  D/G  D
but the boss's got her workin overtime

chorus
                   C
(You know) there's only one saturday....

Bridge
 E               E7          Am

  C                            D              D/G D
why can't i find my feet when i'm fallin down
