Jack’s Big Music Show was a short-lived American children’s puppet show that ran on Noggin, one of Nickelodeon’s sister channels, from September 12, 2005 to October 13, 2007. The series follows Jack, an 8-year old boy who loves to make music. Jack, along with his best friends Mary and Mel, create music. The trio is often accompanied by other puppets or human musicians. At the end of each episode, a big finale song is performed.
