Notes

• This was Joe Raposo's final season as music director. After he passed away on Sunday, February 5, 1989, he continued to be credited as music director until the end of the season, and associate music director Dave Conner became de-facto music director until 1993, when Robby Merkin was hired.
• This was also Northern Calloway's final season as David. After the season finale, Calloway left the show due to medical reasons with the explanation that David moved away to be with his grandmother, and that ownership of Hooper's Store was turned over to Mr. Handford.
