Cm                                        Ab       G 
Must have left my house at eight, because I always do 
                                                         Cm 
My train, I'm certain, left the station just when it was due 
                                              Bb 
I must have read the morning paper going into town 
    Bb                                      Bb7               Eb 
And having gotten through the editorial, no doubt I must have frowned 
 
Chorus
  Eb                                            Bb 
I must have made my desk around a quarter after nine 
     Bb7                                                   Eb 
With letters to be read, and heaps of papers waiting to be signed 
  Ab                         Eb/G                              Fm 
I must have gone to lunch at half past twelve or so, The usual place, the usual bunch 
                                    Dm7               G                          Cm 
And still on top of this I'm pretty sure it must have rained, The day before you came 
 
Verse
Cm                                      Ab        G 
I must have lit my seventh cigarette at half past two 
    G7                               G7/B    Cm 
And at the time I never even noticed I   was blue 
                                         Cm/D            Bb 
I must have kept on dragging through the business of the day 
                           Bb7                    Bb/D  Eb 
Without really knowing any-thing, I hid a part of me  a-way 
 
Chorus
Eb                                                    Bb 
At five I must have left, there's no exception to the rule 
  Bb7                                                   Eb 
A matter of routine, I've done it ever since I finished school 
    Ab                        Eb/G                           Fm 
The train back home again, un-doubtedly I must have read the evening paper then 
                                       Dm7           G                         Cm 
Oh yes, I'm sure my life was well with-in  its usual frame, The day before you came

Verse
  Cm                                Ab6              G 
I must have opened my front door at eight o'clock or so 
    G7                                        G7/B     Cm 
And stopped along the way to buy some Chinese food to  go 
                                               Bb 
I'm sure I had my dinner watching something on TV 
                                                 Bb7           Eb 
There's not, I think, a single episode of Dallas that I didn't see 
 
Chorus
  Eb                                           Bb7 
I must have gone to bed around a quarter after ten 
                                              Bb7/D   Eb 
I need a lot of sleep, and so I like to be in bed  by then 
  Ab                          Eb/G                              Fm 
I must have read a while, The latest one by Barbara Cartland or something in that style 
     Fm                           Dm7            G7                  Cm 
It's funny, but I had no sense of living without aim, The day before you came 
 
Chorus
    Ab                        Eb/G                                Fm 
And turning out the lights, I must have yawned and cuddled up for yet another night 
                                     Dm7                G7                   Cm 
And rattling on the roof I must have heard the sound of rain, The day before you came
