Verse 1:

We can call Mrs. Johnson to keep the kids a day or two.
Take the early flight to Florida, just the way we used to do.
Have room service bring us breakfast, make love all through the day.
If We're Not Back In Love By Monday, we can go our sep'rate ways.

Chorus:
If We're Not Back In Love By Monday we can't say we didn't try.
Just before we bury our love, Let's make sure we've let die.
Sleep a few more nights together, say the things we used to say
If We're Not Back In Love By Monday, we can go our sep'rate ways.

Verse 2:

We could find that little cafe with funny sounding name.
Get the table by the window, I'll say I love you once again.
If the vi'lin player's still there, we'll dance until the break of day.
If We're Not Back In Love By Monday, we can go our sep'rate ways.

Chorus
