Rachel Platten , who grew up in Newton Centre, has come a long way from her days of a cappella and mediocre roles in musicals at Buckingham Browne & Nichols. Over the weekend she had the biggest night of her career to date when she joined Taylor Swift onstage to perform “Fight Song” before a crowd of around 50,000 in Philadelphia. On Monday, Platten’s 2015 single rose to No. 1 on the iTunes song charts.

Platten, who spoke with us after the big night, said that when Swift introduced her, she “almost started sobbing out of gratitude.” Instead, she summoned the steadiness she saw in Swift. She said that looking out at the crowd was “overwhelming” and felt “incredibly right.”

Platten met Swift for the first time earlier this month, following Swift’s concert in Pittsburgh. After their managers introduced them, Swift invited Platten to hang out backstage with Vance Joy , Little Big Town, and Kelsea Ballerini ; this evolved into an impromptu dressing-room jam session, well documented on Swift’s Instagram.


Speaking with a slightly hoarse voice from her home in New York (where she was happy to be reunited with her puppy, a rescue mutt, after about a month away), Platten said she is busy working on a record and rehearsing for her upcoming tour with Colbie Caillat and Christina Perri , which opens close to home July 10 at Mohegan Sun Arena.
