Odd and very dated comic song recorded by Rosemary Clooney and Marlene Dietrich in the early 1950s

Just when you thought you had endured the last of Midweek Madness, it's back. And, for no evident reason, it has decided to foist something truly mad on you -- "Dot's Nice, Donna Fight," sung by two great artists, Rosemary Clooney and Marlene Dietrich in the early 1950s.

I heard it and I still don't believe it. But the harpsichord is such a classy touch, no?
