Shawn Mendes and Khalid performed their new song, “Youth,” which was written in response to the terror attacks that took place in Manchester and London last year. Shawn and Khalid brought the choir members from Marjory Stoneman Douglas High School, a school that endured a shooting just two months prior to Shawn’s song ‘Youth’ dropping. Especially with the recent shooting at Santa Fe High School, this song was definitely needed last night.
