I am watching the 2004-2010 ABC TV series Lost on Netflix. I didn't watch it or anything on ABC network TV in 2004-2010, so I don't know the answer to this question.
What I'm talking about: At the start of (or before?) each episode of Lost as shown on Netflix, there is a still image of the Lost logo and cast, and the ABC logo, and the sound of some people chanting a wordless song like "Oh oh oh ah oh".
Is that "song" specifically for Lost, or is it just an ABC theme song (or imaginary spontaneous excitement of the ABC audience?).
