"Help! It's The Hair Bear Bunch!," which was made under the working title "The Yo-Yo Bears," has been one of those Hanna-Barbera shows that the casual fan liked while many others looked down on with disdain. For what it was worth, it wasn't a Scooby Doo clone, which began permeating Saturday morning TV (H-B's "The Funky Phantom" debuted on ABC the same 1971 season).
"Hair Bear Bunch" actually owed more to "Hogan's Heroes" than anything else. Hair Bear was most certainly Col. Hogan (with a touch of Sgt. Bilko), and zookeepers Eustace P. Peevly and Lionel J. Botch the show's Col. Klink and Sgt. Schultz. The series itself was a quite inoffensive comedy of manners that was really nothing more to Hanna-Barbera than a tax write-off. It aired during the 1971-72 season on CBS, was shelved for a year, then brought back Sunday mornings in 1973 and moved back to Saturdays in February 1974.
