The Kentucky Wonder Bean

 
 
The Song:

In order for it to feel more authentic, Beck filled out his Song Reader book with fragments of songs and melodies, as well as fictional album collections and made-up song titles. The back of "Saint Dude" lists five such albums, and "The Kentucky Wonder Bean" is part of The Manly Family Song Album, and is copyrighted.

Many of the titles on the back of "Saint Dude" are references to older songs, and "The Kentucky Wonder Bean," from what I can tell, seems to be referring to a nickname for a sheet music musician, Walter Peterson.
