"Without further ado" is an expression which means immediately, without further delay or fuss. It is used when you want to say that something shall immediately commence, like in this video here. "Ado" itself means unnecessary fuss, attention, or worry. Ex: Without further ado, let's begin! Ex: He started performing without further ado. Ex: So much ado over nothing!
