Even those I'm sure are all added on during post production. Price is right Definatly, as the audiences screams would drown out any sound system.
That's right. When I attended a taping of TPIR, you didn't hear the intro music, instead it was only Rich's voice that you would barely amongst the loud screams, shouts, and excitement. That continues on when Drew Carey comes out of the doors and everyone gives him a standing ovation. Eventually, they calm down and you then hear the music whenever they show a prize.
