The Muppet Show - Loretta Lynn
The Loretta Lynn episode takes place at a railroad station instead of the theater due to it being fumigated, so the opening and closing were changed to go along with it. Though it was less "Special Edition" and more "Stylistic Suck", with off-key opening and closing themes with mangled lyrics and a (badly) hand-drawn Muppet Show sign.
