Look to your left, and to your right . . . definitely be safe out there; which does not have to keep you from considering the following words:
"We need to take you back in time, when music made us all unite".
So smile, and Feliz Carnaval.
And listen to my favorite Marchinha below. Yes, I know: you are too cool to actually imagine that a song by Jessie J could sum up the spirit of Carnival (oh blasphemy); but give it a chance.
