A new "ultimate mix" of Band Aid's *Do They Know It's Christmas?* is set for release to commemorate the charity single's 40th anniversary.

Producer Trevor Horn has crafted this version by blending vocals from the original 1984 recording with those from the 20th and 30th-anniversary editions in 2004 and 2014. This mix brings together voices of performers from different eras, including Harry Styles, Chris Martin, Sam Smith, and Ed Sheeran from the 2014 lineup, alongside original contributors like Bob Geldof, Boy George, Phil Collins, and Sting.

The track will also feature dual contributions from U2's Bono, who recorded parts for both the 1984 and 2014 versions.

Additionally, the voices of late icons George Michael, who passed away in 2016, and Sinéad O'Connor, who passed last year, will be included posthumously.

Accompanying these vocalists is a band featuring legendary musicians such as Sir Paul McCartney, Queen’s Roger Taylor, Radiohead’s Thom Yorke, and Blur’s Damon Albarn, among others.

The "ultimate mix" will first air on British radio on November 25, marking the exact 40th anniversary of the song's original recording, before becoming available for streaming.

A compilation album that includes the original 1984 version, the Band Aid 20 and Band Aid 30 versions, and the new mix will follow on November 29, with proceeds going to the Band Aid Trust.

For the anniversary, Oliver Murray has also created a new music video, featuring David Bowie introducing the track and clips from Michael Buerk’s BBC report on the holiday classic.

Geldof, who co-founded Band Aid and co-wrote the song with Midge Ure, mentioned earlier this year that he was developing a supercut for the 40th anniversary, envisioning “Harry Styles beside a young Bono” in a mix that bridges generations.
