Oh yes,I have seen that show.

It's somewhat humorous,that she'd make that error but overall,I found it a little ridiculous too.
C'mon..."The Wreck of The Gordon Lightfoot" ?
Even someone not "that" into music knows that doesn't sound like a song title.
If any of you have ever seen Ted Danson's show,"Becker".
There's a character on there named Bob who one day at the diner (near Dr. Becker's office)sits and listens to the female owner's story about how much she loved her last boyfriend.
She tells how they were always fighting and Bob says to her,"Geesh!...What was you two's song,"The Wreck Of The Edmund Fitzgerald"?! :D
(Something like that.)
