VIDEO: Katy Perry, Coldplay’s Chris Martin, and U2’s Bono Honor the Class of 2020 With Musical Performances

U2’s Bono, Coldplay’s Chris Martin, Katy Perry, and Lady Gaga were among the many artists and celebrities who performed songs and delivered commencement speeches on Sunday as part of YouTube’s digital graduation special “Dear Class of 2020.”

Bono kicked his segment off with some words of wisdom and healing before breaking into a star-studded rendition of U2’s inspirational single “Beautiful Day” (above), remixed by recent Stern Show guest Finneas O’Connell and featuring contributions from Martin, Camila Cabello, Noah Cyrus, Cynthia Erivo, Ty Dolla Sign, and more.

Katy Perry, meanwhile, took the virtual stage to perform her new song “Daisies” and her uplifting 2010 anthem “Firework” (below). She also offered some words of wisdom for viewers. “Let’s turn those tassels and make it kind of official — whether you’ve got a real cap and a tassel or an iPhone taped to a pizza box. This is the moment for everyone around the globe to graduate at once. No matter where you are, remember: The tassel goes from right to left,” the visibly pregnant pop star said.

“Dear Class of 2020’s” other performers included Lizzo, Chloe x Halle, and the Korean boy band BTS. Additionally, Lady Gaga delivered an impassioned speech about uprooting racism while former First Lady Michelle Obama, Beyoncé, Alicia Keys, and even “The Simpsons” also made appearances.
