The Fabulous Five
Band made of The Three Bears of fairytale fame (all on saxophones) and Peg from the animated PBS children's show Peg+Cat. Formerly The Fabulous Four, they need a drummer. Cat declines, so Pig joins. Pig, of the Three Little Pigs also of fairytale fame, was formerly with vocal trio The Terrific Three with his brothers.
From "The Three Bears Problem/The Giant Problem" episode (Oct. 2013).
