However, if you ask a lot of people how they know the song they're going to let out a "Woo" because they know it as theme song of Ric Flair. Any great wrestling song has to fit the character. This one is perfect for Ric Flair because it starts out slow as if you're waiting for him to make his entrance, then he does and there's a crescendo as the loud music plays. It's the moment when Flair makes his presence known for the world. Hearing him come out to any other song on a regular basis would have been weird. This one is so right for Flair. When Flair worked for WWE, they used the same thing. His return to the company in 2001 saw them add a "Woo" to it at the start because most WWE songs have a signature phrase by the wrestler at the start of it. That's just good marketing on their part.
