This is a simple sub plan that uses a YouTube video of 4 Golden Buzzer winning choirs on America's Got Talent and Britain's Got Talent.
The link is below:
Have your students watch the video, pausing after each choir to answer the first side of the worksheet. Then answer the second side after they've finished watching the entire video.
The video itself is 20 minutes. The whole lesson should take about 40 minutes if you stop in between each group.
