Firework

Hi, everyone!

I've just come across this video on Youtube and thought it might be interesting to you. See if you can understand what they say and ask me in class for clarifications. The text below is an excerpt from the video's info box.

"Katy Perry and Jodi DiPiazza sing "Firework" at the Beacon Theater in New York. "Night of Too Many Stars: America Comes Together for Autism Programs" is hosted by comedian and presenter Jon Stewart and raises money for autism programs, schools, and services all over the USA".
