Goodnight vienna

Generally means ..its all over, as in, and then it was Goodnight Vienna. I know its a song, and been used by one football commentator, but what was its origin?

I think Don Meredith was refering to the Wagnerian fat lady of the Austrian opera. He also refered to a song "Good Night Irene" in his color commentary towards the end of a football game that should have been terminated early on.
