May 30 (UPI) -- Gladys Knight, Vince Gill, Sara Bareilles, Alan Jackson, Denyce Graves, The Four Tops, Brian d'Arcy James and Bailee Madison will be seen singing during Sunday's broadcast of the National Memorial Day Concert.
The event will also be available via the Armed Forces Network, Facebook, YouTube and the PBS website.
Mickey Guyton performed the national anthem, and special tributes were paid to American nurses from the Vietnam War; the 20th anniversary of 9/11; and the 70th anniversary of the Korean War.
"Tomorrow is Memorial Day, a solemn day of remembrance and honor for those who have given their lives in service to our country," Sinise wrote on Facebook Sunday.
"Tonight we pay tribute to our fallen heroes and all who have served with the National Memorial Day Concert on PBS."
The Forrest Gump, Apollo 13 and CSI: NY star wrote about the importance of the concert in his memoir, Grateful American: A Journey From Self to Service.
"The idea is to unite the country in remembrance and gratitude for all who have served and who have sacrificed their lives," he said in the book. "Whether by participating or watching, we as a country can say thanks -- and that we do not forget."
