The rock icon lost his battle with cancer in January and has been the subject of many musical tributes in 2016, and now three of country music's biggest acts will perform a cover of his classic Heroes for the TV charity drive, according to Taste of Country magazine.
The live performance will be taped during the 2016 ACM Honors ceremony in Nashville, Tennessee, but it won't air until the Stand Up To Cancer telecast on September 9.
Urban's father, Robert, lost his battle in December last year, while Westbrook's sister, Joyce Marie Westbrook Morgan, passed away from the disease in November 2015.
In addition to the country trio, Celine Dion is also slated to perform at the telecast, paying tribute to both her husband Rene Angelil and brother Daniel, who died days apart in January this year, while her brother-in-law, Guy Poirier, is currently fighting cancer in her native Canada.
Ben Affleck, Matthew McConaughey, Emma Stone, Anna Kendrick, and Ken Jeong have also signed up to appear.
