At the inauguration ball, Jennifer Hudson performed Al Green's 'Let's Stay Together' while the President and his First Lady shared the dancefloor, and Alicia Keys added a special twist to 'Girl on Fire.' Even rockers fun. wanted in on the celebrations with their performance of 'We Are Young' at the inaugural ball. So let's get a recap... with GIFs!
