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. "I've Got Hives" is listed as part of the collection of manly hymns, Hymns For Him.

While a lot of the song titles on Hymns are references to older sheet music/songs, I saw no evidence of "I've Got Hives" being an old composition (or a new one even).
