President Abraham Lincoln delivered his historic Gettysburg Address 150 years ago today in Pennsylvania, calling for a “more perfect union” in which “all men are created equal” while the bloody Civil War raged on. To commemorate the iconic speech today, a Dedication Day ceremony is being held at the Soldiers’ National Cemetery, the battlefield site where Lincoln delivered it on November 19, 1863. 

On the chance you can’t make it down to Pennsylvania, you can pay homage to Lincoln’s words by watching a whole bunch of celebrities and everyday Americans recite the speech.

Most people have memorized the opening phrase: “Fourscore and seven years ago, our fathers something something,” and in anticipation of the anniversary, documentary filmmaker and history buff Ken Burns encouraged citizens to commit the entire two-minute address to memory, recite it on camera, and send in the footage.

Scores of people obliged, including five US presidents—Barack Obama, Jimmy Carter, the George Bushes, and Bill Clinton—and a mess of celebrities like Bill Gates, Taylor Swift, Steven Colbert, and Steven Spielberg. A collection of the videos are gathered at learntheaddress.org, the website created by Burns to commemorate the event, and promote his new documentary about the Gettysburg Address, The Address, coming out in April.

In an interview with USA Today, Burns said that especially in today’s fractured political climate, the timeless oration should serve as a call for national unity. “By memorizing it, it will be internalized,” he said.

Whether or not you agree with Burns’ faith in the power of rhetoric, it’s worth taking two minutes to watch or read the speech today. A century-and-a-half later the president’s plea for equality and unity still relevant—though it’s worth mentioning that Lincoln’s ideals were ahead of their time; black soldiers were denied burial at the very cemetery where the speech was delivered. 

Nevertheless, as the legend goes, renowned Massachusetts orator Edward Everett—the keynote speaker at the 1863 event, from whom Lincoln stole the show—told the president, “I should be glad if I could flatter myself that I came as near to the central idea of the occasion, in two hours, as you did in two minutes.”

The full text:

Fourscore and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal. 

Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. 

But, in a larger sense, we cannot dedicate—we cannot consecrate—we cannot hallow—this ground. The brave men, living and dead, who struggled here, have consecrated it far above our poor power to add or detract. The world will little note nor long remember what we say here, but it can never forget what they did here. It is for us, the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us—that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion; that we here highly resolve that these dead shall not have died in vain; that this nation, under God, shall have a new birth of freedom; and that government of the people, by the people, for the people, shall not perish from the earth.
