Kevin Jonas is entering a new chapter in music! During the Jonas Brothers’ Greetings From Your Hometown Tour stop in Boston on Saturday, Aug. 23, Kevin, 37, surprised fans as he performed his first-ever solo song, “Changing,” onstage for the first time. In a video posted by a concertgoer on X, Kevin told the audience as he appeared onstage with a guitar in hand, “I’m super nervous, so bear with me,” while music to the intro of the song played. He then started singing the lyrics to the new track as the crowd cheered.
