The Minstrels, wandering musicians led by the enigmatic and wise Cantus the Minstrel, arrive at the Fraggles' cave, announcing that a medley will be sung the next day. Red is chosen as Medley Leader, but the medley won't begin until Red finds the song inside her -- and she doesn't know where to look!
Meanwhile, Doc and Sprocket work on a new type of doorbell.
This episode reveals another clue about the size of Fraggle Rock. The Minstrels -- who Gobo and his friends have never seen before -- arrive in the cave and explain that they travel around, "finding Fraggles in distant caves," and leading medleys. For Cantus and the Minstrels to have enough places to go for them not to have been here within recent memory, the Rock must be huge.
This episode is the first appearance of Cantus and the Minstrels, who reappear whenever music and wisdom are needed. He is also one of the two recurring characters performed by Jim Henson, the other one being Convincing John.
If a Fraggle "borrows" Cantus' magic pipe in order to learn their inner song, the pipe will take a mind of it's own and drag that Fraggle around until Cantus tells the magic pipe to stop. Also, it will leave an odd-shaped mark on the Fraggle's hand that is similar to the one on Cantus' hand....at least until the Fraggle learns their inner song. In other words, Cantus claims that this is the magic pipe's way of saying "MNH-MNH."
