Wide Receiver (Theme from NBC Football) by John Williams 

No, this is a new theme he wrote for the college football league

Yes

I'm thinking about Imagi Animation Studios and Gatchaman (Battle Of The Planets), with Galactor and the International Science Organization.

I commented in another video with this theme that this song feels like it could be put in Star Wars and nothing would skip a beat. This sounds like if the Rebel Alliance got their own Imperial March equivalent.

I listened to Fox's football theme music. Then listened to this. Actually bowed down then saluted to this. Such awe inspiring composition. All hail Sir John Williams.
