Synopsis

Jack takes a break everyday from his busy kid schedule to visit his favorite place in the worldâ€”his backyard clubhouse. Here he can do what he loves bestâ€”create and enjoy music, sing, dance and have a ball with his friend Mary, his faithful dog Mel and all of his neighborhood pals who stop by. Anything can happen in Jackâ€™s clubhouse.

At the end of each episode, a big "finale" song is played.

The characters play music in every episode and are often accompanied by other puppets or human musicians.

Each episode starts with Jack's off-screen mom calling him that he has to leave for an activity soon.

Each episode also usually features two music videos by children's musical artists and a performance by the Schwartzman Quartet about the episode's theme.
