This ain't the first time R.J. Williams (Kit) and Ed Gilbert (Baloo) worked on a cartoon together. This troper used to have a video tape of an NBC cartoon called Kissyfur. The title character was Kit; his dad Gus was Baloo.
Keep Circulating the Tapes: The last 11 episodes were completely unavailable on DVD for many years, but they were finally released exclusively through the Disney Movie Club in June of 2013. This also makes TaleSpin the first of The Disney Afternoon shows to completely avert this trope.
The Other Darrin: Kit was voiced by two actors—first Alan Roberts, then R.J. Williams. "A Bad Reflection on You" uses both Roberts and Williams; it's difficult to tell them apart, but you can do it if you're familiar with the subtle differences in their voices and you listen carefully.
R.J. Williams is Kit in "A Bad Reflection on You" part 1, and Alan Roberts is Kit in the "A Bad Reflection on You" part 2. The key to telling their voices apart is that R.J. Williams, who was Kit in "Mommy For A Day" and "Captains Outrageous" sounds a little bit older than Alan Roberts who was Kit in "Stormy Weather" and "The Time Bandit".
Phil Harris was apparently to play Baloo again for the show, however his vocal range was thought to have aged too much following auditions, and soundalike Ed Gilbert took the role instead.
Some people who worked on the show, however feel Phil Harris still sounded young enough to voice Baloo, and the real reason he was passed over was because he would have been too expensive to pay every episode.
In the writers' bible, Shere Khan was named "Mr. Downs", and Don Karnage was named "Anthrax" (and wore no pants). Also, Spigot and Dunder were originally designed as cats.
Don Rosa wrote "It Came from Beneath the Sea Duck" and "I Only Have Ice for You".
