re: Songs that specifically name (a proper name) a fictional character in the title or lyrics

Hey There Delilah

Fun fact: In the movie Singles, though it’s not on the soundtrack, there is a part in the movie where you hear an early version of Spoonman. This was a year or so before Soundgarden released it on an album.

Ooh- we’re gonna need a judge’s ruling on “What’s the Frequency, Kenneth?” It was written after Dan Rather was assaulted by a man on the street who kept asking him “What’s the Frequency, Kenneth?”

Kenneth is obviously not Dan Rather’s name but the song is referring to him. Is this a fictional character or not?
