The Daffy Duck Show (1978) Season 1 Episode 29

The lyrics for the song "What's Up, Doc?" are heard for the first time during What's Up Doc?. The song's tune had been first used a few years earlier, usually over the title credits of other Bugs Bunny cartoons. This cartoon appears in Looney Tunes Golden Collection, Volume 1, CD 1. It is followed by several other Bugs cartoons using the instrumental version of the theme in the intro.
