"Hamilton's" Lin-Manuel Miranda is very excited about opening night of his musical in Los Angeles.

There's a reason, however, why this opening night — even more than the ones in New York, Chicago, and San Francisco — truly is "the big magillah," he said.

The Broadway star on Aug. 16 is raffling off a totally VIP experience for lucky fans who've expressed support for immigrants and refugees online.

As Miranda explained in the video above, you can win two tickets to the L.A. opening of "Hamilton" — as well as airfare, hotel stay, and access to a star-studded after-party — if you:

• Donate $10 toward the Immigrants: We Get the Job Done Coalition, a group created by the Hispanic Federation that helps unify efforts from various organizations fighting for immigrants, refugees, and asylum seekers in the U.S.
• Create a video of yourself singing a song (or part of a song) from "Hamilton." In the video, challenge at least one friend to do the same.
• Post the video online using the #Ham4All hashtag.

In the hours following Miranda's ask, the internet began to flood with fans pining for their shot to win. Among them were quite a few big names, too.

Eva Longoria blasted out the lyrics to "Alexander Hamilton."

Ben Stiller and his daughter, Ella, went all in on "Non-Stop."

Shonda Rhimes basically proved she should be in the actual cast of "Hamilton," honestly.

Kelly Clarkson gave us a taste of "It's Quiet Uptown" (and left us wanting more!).

NBA champ Stephen Curry and his wife, Ayesha Curry, brought their rap A-game.

The Harlem Globetrotters made clear they're also not "throwing away their shot."  

Matt McGorry's King of England was downright breathtaking.

As was Justin Baldoni's.

Gina Rodriguez used some backup vocals for an assist, and it came out beautifully.

And Sara Ramirez flaunted a nice set of pipes you don't normally hear on "Grey's Anatomy."

Celeb videos and Broadway tickets aside, the Immigrants: We Get the Job Done Coalition is a remarkable effort you should definitely support.

Uniting goals from "an all-star Avengers team of 12 organizations" (as Miranda described it), the coalition helps immigrants, refugees, and asylum seekers in the U.S. by providing legal representation, fighting for changes in public policy, launching awareness campaigns to change hearts and minds, and more. These services truly are critical — especially under the threats of the current administration.
