Planning the end of the course

Hi everybody,
I am planing tha last week term/course. I usually use songs in my lessons. I love it. Apart of making a reading with rythm, the students pull down the wall of shame they sometimes have in front of them and it doesn't let them speak fluently.
As most of my students love programs such as"Operación triunfo", o "Al pie de la letra" I have proposed them a karaoke for the last week.
One, two or even three people per group. They choose the song they like, of course I try to help them choose songs which are possible to sing for them. I mean, not very fast rythms and always try a standard english. Next, they will work it, looking up phonetics and meanings in order to have a deeper knowledge of the song.
I can say they have accepted the idea very well because they are already working it. Even they propose singing in the final festival. Not necessary to say that I will also sing....
God save us.......!
