Terrific movie, but a question

Rating: 10/10 (29 October 2005)

George Clooney and David Straithairn have done a superb job in outlining an all-but-forgotten episode in our history, that has eerie similarities to events of our own time.
Murrow is said to have paved the way for advocacy "journalism" of the Limbaugh-O'Reilly type, but he held himself to a much higher standard of accuracy than today's ranters.
I enjoyed this film very much, but I wonder why the Diane Reeves jazz vocals were inserted. They are, in themselves, wonderful, but they seem to have no function in the film other than to make it longer. They aren't even consistent with the period.
In any case, go see it. The story (and the music) are very well done.
