Phil Hartman has voiced all these characters (thanks for the names, Alex!) at least once before he died in 1998.

Not at all😉

👎 Is that true? This site disagrees but I must confess that I didn't check who voiced the characters when composing the question.

Yes, two of the characters were only supposed to appear once, when he did the voice (GPT said, after I asked him about the voiceover by Hartman, who I knew was dead). I don't know myself.

Maybe they're all tied together by their strong connection to the past?

Abe Simpson , stuck in the past, always rambling about his youth.

Troy McClure, longs for the glory days when he was a star.

Sideshow Bob, regrets his failures but sometimes mourns his lost dream.

Disco Stu , trapped in the '70s, for him, disco never died.
