"The puppet characters included Garfield Goose; Garfield's nephew, Chris (born on Christmas day); Romberg Rabbit, a former magician's assistant; Ramona Rabbit, Romberg's girlfriend; Beauregard Burnside III, a bloodhound; Macintosh Mouse; Mama Goose and Ally Gator. The puppets never spoke. Garfield would clack his beak, and Thomas interpreted for him."
Anyone growing up in Illinois during that time can immediately connect by just saying: "Hotdogs, hamburgers, spaghetti and meatballs!" or "Remember Journey to the Beginning of Time?" and of course "I'm Hardrock" "I'm Coco" "I'm Jo!" With the name "Jo" sung in the deepest register one can muster.
