This is a great activity using the Katy Perry video: LAST FRIDAY NIGHT, which is very funny. It's made for Pre-Intermediate Level, but it can be adapted. I worked complete the gaps (conversation part), vocabulary (many new words for students) and the Song (working with its vocabulary as well). The result was great in classroom. Enjoy it !!! (Be careful: Use it only with young adults up (age) because of the song language, ok!).
