Watch Celebrities Sing ‘Fight Song’ at the Democratic Convention

A group of celebrities performed an a cappella version of Hillary Clinton’s campaign song for a video showed at the Democratic national convention Tuesday night, though it was not exactly pitch perfect.

Introduced by actress Elizabeth Banks, who also hosted the second night of the convention, the three-minute video featured actors and musicians—not all of whom could hit the notes exactly—performing Rachel Platten’s “Fight Song,” a popular pop song adopted by the Clinton campaign at its rallies.

The video drew on Banks’ role in the a cappella “Pitch Perfect” movies while referencing the popular will.i.am-produced “Yes We Can” video from 2008 featuring celebrities singing along to a Barack Obama speech.

A number of the “Pitch Perfect” cast pitched in, including singer-songwriter Ester Dean, Ben Platt, Kelley Jakle, Hana Mae Lee, Shelley Regner and John Michael Higgins. Actresses America Ferrera and Eva Longoria, two Clinton surrogates who spoke at the Democratic convention, also make appearances.

Here are some other celebrities in the video:

Musicians: Platten, Dean, pop singer Mandy Moore, a cappella singer Mike Tompkins, musical theater singer Ellen Greene, singer-songwriter Sia, Broadway star Kristin Chenoweth and Frozen‘s Idina Menzel.

Actors and actresses: Modern Family‘s Jesse Tyler Ferguson, Jane Fonda, Friday Night Lights‘ Connie Britton, talk show host Aisha Tyler, Kathy Najimy, The West Wing‘s Mary McCormack and director Rob Reiner.
