WATCH: Stars unite for Hillary Clinton in 'Pitch Perfect'-inspired 'Fight Song'

MANILA, Philippines – With on-point harmonies and no musical instruments involved – this is how some stars show their support for Democratic presidential nominee Hillary Clinton.

A star-studded video featuring Rachel Platten's "Fight Song" – in the vein of the Pitch Perfect movies – was aired on the occasion of Hillary Clinton's proclamation as the Democrats' presidential bet at the Democratic National Convention on July 26, Tuesday (July 27 in Manila).

Stars such as Elizabeth Banks, Sia, Eva Longoria, Idina Menzel, Ian Somerhalder, Kristin Chenoweth, Mandy Moore and more – including some from the cast of Pitch Perfect – joined forces in this video in a show of support for Hillary as she goes up against Donald Trump, the Republican nominee.

The song goes, at one point: "I might only have one match / But I can make an explosion" – an apt line for Hillary's "fight."

Elizabeth Banks produced the music video, as she has done with the Pitch Perfect films. –
