The virtual 'post-graduation party' took place on YouTube yesterday

The 'Dear Class of 2020' special that took place on YouTube yesterday certainly pulled in some big names.

The 4-hour special was intended as a celebration of all of the high school and college graduates who are missing their graduation ceremonies because of the coronavirus pandemic, and was described as a "celebration bringing together inspirational leaders and artists to celebrate graduates, their families, and their communities."

Some of those 'inspirational leaders' were drawn from the political world - like Barack and Michelle Obama - but most were from the entertainment world, such as the star-studded cover of U2's 'Beautiful Day'.

Beyonce's commencement speech certainly went down very well with audiences, as she touched on the recent deaths of George Floyd, Ahmaud Arbery and Breonna Taylor, as well as sexism in the music industry, stressing the importance of young people using their voices.

"Not enough black women had a seat at the table," she said. "So I had to go and chop down that wood and build my own table. Then I had to invite the best there was to have a seat. That meant hiring women, men outsiders, underdogs, people that were overlook and waiting to be seen."

K-Pop boyband BTS also gave a commencement speech, as well as performing:

Lizzo gave a performance with her flute:

Lady Gaga also gave a speech:

Katy Perry also performed her song 'Daisies':
