Guess this song!

Just say the title or the author

You're so late getting home from the office, Did you miss your train?
Where you caught in the rain?
No, don't bother to explain.
Can I fix you a quick martini?
As a matter of fact
I'll have one with you,
For to tell you the truth
I've had quite a day too!

Guess who I saw today, my dear!
I went in town to shop around
for something new,
and thought I'd stop and have a bite
when I was through.
I looked around for someplace near,
and it occurred to me
where I had parked the car,
Tehre is a most attractive French cafe
and bar.
It really wasn't very far.

The waiter showed me to a dark,
secluded corner,
And when my eyes became accustomed
to the gloom,
I saw two people at the bar
who were so much in love,
that even I could spot it clear
across the room.

Guess who I saw today, my dear!
I've never been so shocked before.
I headed blindly for the door.
They didn't see me passing through,
Guess who I saw today?
Guess who I saw today?
Guess who I saw today?
I saw you!

Guess who I saw today, my dear by Marilyn Maye?

Yep, heard it today and it sounds pretty cool how her husband cheats on her.
