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.
"Swingin' In The Clouds" does not seem to be any particularly specific musical reference from what I can tell.
