[Intro]
Dm C F Bb
Dm C F Bb

[Verse One]
Dm                      C          F               Bb
Tonight I'll sit at the bar on St. Mark's where we met
   Dm                C             F              Bb
If I stayed away from all the places we have been together
Dm            C
I couldn't go anywhere
F  Bb
Anymore
    Dm                     C           F               Bb
You said I should find somebody new to love me like we choose it
    Dm                         C                  F              Bb
You want to believe that there may be a sweetness to a temporary distance

[Chorus]
Dm                C
Good grief, baby, there's no such thing
F                 Bb
Good grief, baby, there's no such thing

[Verse Two]
         Dm                    C
Winter's comin' again and I've started to spend
         F                    Bb
Then I'm out and I smell your perfume
       Dm                    C
Now it hurts when I open the medicine cabinet
F                Bb
And see your red lipstick

[Chorus]
Dm                C
Good grief, baby, there's no such thing
F                 Bb
Good grief, baby, there's no such thing

[Bridge]
Dm             C
If you were to leave
F                 Bb
There would be no silver lining
Dm         C
I don't believe
        F             Bb
I would get out on my feet
Dm              C        F          Bb
There's no such thing as good, good grief
    Dm              C        F          Bb
No, there's no such thing as good, good grief

[Chorus]
Dm                C
Good grief, baby, there's no such thing
F                 Bb
Good grief, baby, there's no such thing
Dm                C
Good grief, baby, there's no such thing
F                 Bb
Good grief, baby, there's no such thing
