The Heart of Saturday Night - guitar chords and comments

Lyrics without distraction HERE

Title song from Waits' second 1973 album. The significant upright bass almost forces your thumb to slide up and down the first string; muting the sixth. The () indicates this, but it is not really necessary. Neighter other thumb tricks I haven't mentioned. This song is a diamond in roots music, but curiously not covered by too many artists. Maybe because the original was fundamental, and thus hard to interprete.
G                 (G/A) (G/B)      (G/A)
well you gassed her up  behind the wheel
          C                                 Am7
with your arm around your sweet one in your oldsmobile
C                   D       ...D7
barreling down the boulevard
                                 G
you're looking for the heart of Saturday night

          C                    D         D7
then you comb your hair  you shave your face
G        (G/A)    (G/B)   (G/A)
trying to wipe out every trace
C                 Am7
of all the other days in the week
               D              D7              D6            D7
you know that this'll be the Saturday you're reaching your peak
