Several of Hillary Clinton’s most famous and fervent supporters banded together to create a celebrity-infused, Pitch Perfect-style a cappella video for the Rachel Platten track “Fight Song" as a show of support for the Democratic nominee.

Longtime Clinton supporter Elizabeth Banks coproduced the video -- along with Bruce Cohen and Mike Thompkins -- which played during the Democratic National Convention last night (July 26), according to US Weekly.

The video features several celebrities like Mandy Moore, Aisha Tyler, Eva Longoria, America Ferrera, Kristin Chenoweth, Idina Menzel, Jane Fonda, Julie Bowen, Jesse Tyler Ferguson, and more (including Platten herself) singing their own version of “Fight Song," which has been a staple throughout Clinton's campaign.

After the clip ended, Clinton appeared onscreen to address the convention, saying, "I am so happy for this great day and tonight. What an incredible honor you have given me and I cannot believe we just put the biggest crack in that glass ceiling yet.

"Thanks to you and everyone who has fought so hard to make this possible. This is really your victory. This is really your night," she said. "And, if there are any little girls out there who stayed up late to watch, let me just say: I may become the first woman president, but one of you is next."

Clinton made history last night when she became the first ever woman nominated by a major party to secure the Democratic nomination. She's set to run against Republican nominee Donald Trump in the fall.

Check out the Elizabeth Banks-coproduced video of “Fight Song” above, and be sure to stick around to the very end to see Sia -- in all her two-toned, wigged glory -- make a surprise appearance as well.
