I recently did this nsync lesson with my students and most of them seemed to really enjoy it, i briefly talk about nsync and who they are, then show the video bye bye bye first so they can watch it.  afterwards i hand out the worksheet and let them listen to the song 2 more times so they can fill in the missing words.  go over the words as a class and then watch the video one last time now that they have all the correct words. 
theres normally some time left at the end of the class so i just play a game the rest of the time

hope somebody finds this helpful
