And now, a flock of peacocks. The original NBC Peacock from the late 50's lives somewhere on Kris Trexler's website, but here are two others from YouTube.
This one is called the "Laramie Peacock" because the first program it was ever used on was the NBC western "Laramie". The music is a little different here, I believe it was used until 1968.
How about this oddity: a clip of the NBC peacock, with the later (1968?) music, and a custom voiceover by none other than the late Bill Wendell that the following SPORTS program is in Living Color?
