Thanksgiving In Heaven

 
 
The Song:

To make it feel more authentic, Beck filled out his Song Reader book with fragments of songs, and even just made-up song titles. This is one of the titles, listed in Ye Midnight Stars, a collection of "songs from the afterlife." Most of the Ye Midnight Stars titles are humorous looks at death, heaven, the afterlife, etc.

I tried to find if "Thanksgiving In Heaven" is a reference to anything, but it was hard to tell for sure. The phrase itself is used a bit on some religious websites to talk about the literal giving of thanks. Musically, there seems to be a fairly famous Christian tune called "Christmas In Heaven"; also Monty Python has a less-serious song by that name too. Either could've been referenced here!
