An overlooked cover tune X

If you listen to Peter Mulvey's music, you'll notice that he's a generally serious singer-songwriter.  "Wings Of The Ragman" and "Better Way To Go" are two of the first songs of his that come to my mind.  Although there are some bits of humor, Mulvey, for the most part, pairs his introspective lyrics and imagery with acoustic guitar arrangements to match.  It surprised me, then, when listening to his CD, "The Trouble With Poets," to hear him cover Fats Waller's "You Meet The Nicest People In Your Dreams" so smoothly.  I never would have imagined Mulvey, or really, anyone besides Waller singing, "I've searched this universe over, from Wackenacksack to Dover, and now that we have met, how sweet it seems..."  I also didn't expect to hear a piano-and-trumpet melody transferred so gracefully to the guitar and mandolin.  There's a circus-like dancing bear quality to the tune that Waller and Mulvey both capture, which makes it work equally well in either genere.  It's unlike any other tune on "The Trouble With Poets," and Mulvey, to his credit, labels it as the album's intermission.  It's an inspired, unexpected choice.
