Need help remembering an old Tracey Ullman sketch (and song)

[Meltdown]

Probably most famous as launching "The Simpsons," the Tracey Ullman Show was a sketch comedy / variety show from back in the late 80s. Ullman had (has?) a pretty good voice, and there were a number of sketches in which she broke into song -- I remember one that included a spirited version of Elvis Costello's "Radio Radio."

Anyway, I'm trying to remember one where Ullman played an older (lets say 50-60ish) woman. I can't remember what the sketch was about, but it ended with her at the piano, playing and singing a slow, downbeat ballad. I can't remember any of the lyrics, either, but it included something like "love killed the dream." And I'm sure that's not it, because googling that phrase is of no help.

Anybody remember that? Do you know what song that might have been?

Thanks!
