The number one record in the world right now is still "Uptown Funk" by Bruno Mars & Mark Ronson. They are trying to make sure that it stays number one for a while as they showed up on Ellen to perform the funk anthem.
Mars made sure to perform with the crowd right behind him and his crew for a bit so the audience could participate in the performance. A high energy performance as well.-DocFB
