Gimme das Lied, Babe!

While on my bike this evening, as I drove into the tunnel of an underpass, I heard a woman singing in what I considered a fine operatic voice. I could see her up ahead, a silhouette against the exit; she stood beside a bearded man, and she was bent over with laughter.

As I rode past, I called out and said, "Can you sing Mahler's Das Lied von der Erde?"

She replied, "No... but if you come back tomorrow, babe, I bet I could!"
