A popular song with young learners and teenagers. I made this worksheet on request of my students as they love this song and can't get enough! It has a variety of different language activities like gap fills, delete the extra word etc. There is no answer key as I normally do the sheet alongside my students. This is an activity for fun and to practise listening skills, it isn't important to understand the true meaning unless your students want to (mine don't , they just want to sing hence end of lesson fun activity!)
