Many years ago I agreed a copy of the first NBC theme on this track, I don’t recall where I got it and never heard it in use. Never heard the second track, but it’s good, too.
The three tones that have always identified NBC are relevant. The notes are G, E, and C which happen to be the first letters of General Electric Company and reveal its role in the formation of the network.
