For the 1985-6 TV season, Bugs Bunny and the Looney Tunes moved from their longtime Saturday morning network TV home of CBS to ABC. For their first season on ABC, the show went by the title of The Bugs Bunny/Looney Tunes Comedy Hour. The show's opening was definitely not as memorable as CBS' openings were, but I still got a big kick out of seeing this again (I hadn't seen this since it originally aired when I was a kid).
You may have noticed two big omissions from the list of characters the narrator introduces: Speedy Gonzales and Tweety. Tweety was oddly absent from this initial season, he returned the following year to share top billing with Bugs when the show was retitled The Bugs Bunny and Tweety Show (which, of course, had a very successful run on ABC... lasting until the fall of 2000). Speedy's cartoons never showed up on ABC during the entire run of the show (aside from his cameo in the 1979 made-for-TV short "The Fright Before Christmas").
