Retrojunk has lots of vintage TV intros and theme songs from the 70's, 80's and 90's. I love TV themes on Retrojunk and here it is.

That's a very cool site!!

Not to mention they have lots of retro tv commercials from the 80s and 90s. They have McDonald's "Mac Tonight" ads on there. I had been waiting years to see those again! (they don't have the one with him in the city I was looking for, but eh)

Great site!
