With the summer tour coming to a close, Radio.com sat down with Knight, who, among other things, recalled the very first time he heard himself on the radio. He was 16, in his native Boston.

"I was in my living room, [in] the house I grew up in. The song was 'Be My Girl' and it came on an AM station," he said. "There's something about your song being on the radio. It just makes it real. It makes it legit. I was like, 'That's a legit song!'"

Knight said it's a very different feeling hearing the song on the radio vs. in the studio. "When you hear it over and over in the studio or on your cassette player, it just sounds like a studio tape," Knight said. "But then when you hear it on the radio you're like, 'We can be famous!' It made me really excited."
