I 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/D Eb
And having gotten through the editorial no doubt I must have frowned
Bb
I must have made my desk around a quarter after nine
Eb
With letters to be read and heaps of papers waiting to be signed
Ab
I must have gone to lunch
Eb/G Fm
at half past twelve or so The usual place the usual bunch
Dm7 G
And still on top of this I'm pretty sure it must have rained
Cm
The day before you came
I must have lit my seventh cigarette at half past two
