LL Cool J, Ludacris, Barbra Streisand and Pitbull also honored the dead.

P!nk spent Memorial Day honoring the service of America’s veterans, including her dad, Jim Moore, who served in Vietnam. After celebrating last year by inviting Moore on stage at a February gig in New York where they dueted on a song her dad wrote during the war, “I Have Seen The Rain,” P!nk posted the clip on Monday (May 25) to pay tribute to everyone who has served the nation.

“Thinking of all the soldiers and veterans and military families today,” she tweeted. “Sending my love and respect and gratitude for your sacrifice. This is a song my dad wrote while serving in the Air Force in Vietnam. The first song I learned to harmonize to.”

Check out the video of P!nk’s performance of the song, along with other tributes to veterans from LL Cool J, Ludacris, Dolly Parton, Trisha Yearwood, Big Boi, Barbra Streisand, Ciara, Pitbull, Blake Shelton, Ryan Seacrest and others.
