Lady Gaga, Taylor Swift, Paul McCartney, The Rolling Stones, Beyonce and Oprah Winfrey on Saturday headlined a special broadcast of music, comedy and personal stories celebrating those around the world on the frontlines of the coronavirus pandemic.

The two-hour “One World:Together at Home” event, broadcast across multiple television channels in the United States and overseas, featured a Who’s Who of pop culture in the biggest celebrity gathering so far to mark the effects of the virus.

Contributions, all filmed in their homes, also came from Elton John, Jennifer Lopez, Stevie Wonder, British soccer star David Beckham, former US first ladies Michelle Obama and Laura Bush, Andrea Bocelli, Celine Dion, Billie Eilish, Bill Gates and dozens of others.

“I am so grateful for the healthcare workers, the medical workers, all the grocery store workers and delivery people, the postal workers, all the other nonprofits that are working so hard,” said Gaga, who helped organize the event.

“This is really a true love letter to all of you all over the world, and I hope a reminder of the kindness that’s occurring right now,” she added.

The event, led by the World Health Organization (WHO) and the nonprofit group Global Citizen, told the personal stories of teachers and healthcare, grocery, delivery, postal and other workers.
