Rachel Platten's "Fight Song" was one of the young summer's breakout pop hits -- and that was before Taylor Swift got hold of it. On Saturday night (June 6), Platten joined Swift and her pal Kelsea Ballerini backstage at Swift's concert in Pittsburgh to perform a bit of "Fight Song" for an Instagram video:

In the video, which has nearly 1 million likes on Instagram, Swift is shown pounding on a coffee table as Platten helps warble the triumphant chorus of "Fight Song." The self-confidence anthem sounds like Swift's early country-pop oeuvre, and with Swift accompanying Platten in the clip, "Fight Song" sounds even more like a mainstream smash.

"Fight Song" has peaked at No. 28 on the Hot 100 chart, and slipped to No. 36 on last week's tally. Will Swift's co-sign help the song bound up the chart? Time will tell.

Swift will continue her 1989 stadium tour with Vance Joy, while Platten is currently on tour with Colbie Caillat and Christina Perri as part of their The Girls Night Out, Boy Can Come Too trek.
