Sitting at home, the telephone rings. Old girl of mine looking to spend some time. Now my girlfriend's away. I can't see no harm. A couple of drinks and some talk of old times. When the cat's away the mice will play. We had such good time, a bottle of wine, With some old friends of mine. The next thing I knew, we were alone together. We dimmed the lights, our bodies entwined. When the cat's away the mice will play. Then a knock on my door, a spill of some wine. I answer the door, and what do I find? My girlfriend staring at me, boy, what a surprise! Woman in my bed, holding a glass of wine. When the cat's away the mice will play. To make a long story short, she asked how I could do this, In a calm sort of voice. And then without an answer, I mean, what could I say?, I just closed the door and that was goodbye... When the cat's away the mice will play.
