There's a creditable version of Adele's "Hello" available in French!

If your students are fans of the original, try this version sung in French by Sara'h. The video is also captioned in French. (I've attached a gap-fill worksheet and corrected a few grammar errors found in the subtitles.) Again, the age range will be determined by whether your programme is for French as a first language, Immersion, Extended or Core French students.
If your students enjoy it, I'd love your feedback.
