As a way to say good-bye, the senior class of Chislehurst and Sidcup Grammar School (aka Chis and Sid) in Kent decided to make a video with students and teachers dancing to Party Rock Anthem by LFMAO.
Just play the video and enjoy the music, the dance and these guys' imagination.
Also remember that there are a number of sites where you can instantly get the lyrics for thousands of songs, Party Rock Anthem included.
