re: Usain Bolt during National Anthem - Class Act

He is being interviewed by a Spanish reporter when he hears the U.S. National Anthem start playing in the background for a U.S. Medalist on the podium and he immediately stops the interview and goes to a position of attention in respect. When the national anthem was finished he continued the interview. His actions were obviously very genuine and it was automatic for him not like a big thing or something that he even had to think about.
