The band members wore the same outfits across all music videos in Season 1 but wore different clothes for each music video in Season 2.
Laurie Berkner and Susie Lampert are the only human performers to both appear in music videos from the Music Machine and interact with Jack, Mary, and Mel in the clubhouse.
Laurie Berkner was born in France, making her one of the few cast members on the show who were not born in the USA.
"Under a Shady Tree", "Mahalo", and "A Little Biddy Rhythm" are the only songs on the show where Laurie appears without her backup band.
The group appeared in some music videos on Noggin/Nick Jr.'s Move to the Music segments that are not on Jack's Big Music Show.
Bob Golden only appeared in one music video: "Farm Song".
In Season 1, the backgrounds were plain with different pictures on them, the pictures remain the same but the background is a different color in different scenes, and no stage props were used. In Season 2, the plain backgrounds had only 1 color, and were more varied with props.
