Holiday caroling is one of our favorite things to do once Thanksgiving rolls around. And it turns out that A-listers love a good old sing-along just as much as we do!

The latest episode of Jimmy Kimmel Live! included Tinseltown’s finest in a singing session unlike anything we’ve seen before. Backed by Bono and his (RED) organization, which raises money and awareness about the global AIDS epidemic, host Kimmel and the U2 frontman brought together Julia Roberts, DJ Khaled, Neil Patrick Harris, Kristen Bell, Channing Tatum, and Halsey for a star-studded episode that included an epic chorus moment.

As you might have imagined, hilarity soon ensued and Kimmel put his signature flair on the entire evening. The chorus of the song? “If we don’t help people with AIDS, we’re going to hell,” his imploration to help (RED) in its journey to stop the spread of the fatal disease. The Killer’s Brandon Flowers took to the piano to provide the evening’s accompaniment.

Roberts then asked Harris to put his Broadway dancing skills to good use, by asking, “Say, Neil, is there any way we could get you to do some tap dancing for us?” He obliged and brought Tatum in on the fun—with some expert tap dancing and turns, all on the set’s plush fur carpet, of course.

The show isn’t the only thing the stars are doing to raise funds. They are providing once-in-a-lifetime experiences through auction. Taking in a Broadway show with Harris, grabbing tea with Bono and Roberts, going jet skiing with DJ Khaled and unlocking some major keys, and going backstage to meet Hamilton’s Javier Muñoz are just a few of the one-of-a-kind moments available for bidding.

We’d donate to such a vital cause regardless, but these auctions are definitely making giving back so much sweeter.
