Despite his condition, the video shows Jordan to be a happy and energetic little guy who's thrilled by the visit. After a conversation about Spiderman (who apparently came for a visit the day before), Swift asked Jordan what song he'd like her to sing. He wanted a song that he could dance to, and so she wound up playing "We Are Never Ever Getting Back Together." As Swift sang, accompanied by just her acoustic guitar, Jordan bounced along to the beat and chimed in on the chorus.

A video of the visit was initially shared on Jordan's Facebook page, with another version posted on YouTube. The visit wasn't designed to be a big publicity stunt. As a hospital spokesperson told the Boston Globe, Swift simply wanted to stop by and hang out with some of the children. Which is something she has done before. This past March, for instance, she and her father stopped by Hasbro Children's Hospital in Providence, R.I., to visit with the kids and perform.
