I’ve had this earworm for days. My roommate and I think its an old jazz song from the '30s or '40s… rather than an unrecognizable amalgamation of things I’ve listened to over the years.

I tried a couple apps that use artificial intelligence to ID songs. The best they could do is “You Belong to Me”, “How Far I’ll Go”, and “奶与茶”, none of which sound remotely similar.

Don’t recognize it, but I’m damn impressed with your skills at sitting down at the keyboard and rendering your earworm so fluently.
I do recognize the style. 30’s era jazz / ragtime, pre-big-band.
Damned catchy tune! So long as you’re unsure of its provenance, you might want to try copyrighting it and see what happens.
Recognize it. It’s old, as AHunter3 points out, and was/is quite popular. But I’ll be damned if I can name it. I think the chorus contains the lyric ‘Don’t Say Maybe’.
Almost sounds a bit like "Hey Good Lookin’ too, Hank Williams.
Does rather sound like a jam session version of that.
Some of it sounds to like a jazz version of ‘When I’m 64’ by the Beatles
Parts of it sound like “Sixty Minute Man,” which was a hit for Billy Ward and his Dominoes in 1951.
Heck, parts of it sound almost like the music from Super Mario Bros 2…
And part of it sounds like Lulu’s Back in Town, but that’s largely due to the very common chord progression first heard at 0:17 in the OP’s link.
Parts of it sound like one, two, three strikes, you’re out…
Yeah, I was definitely hearing this at the end of the first or second verse. I also heard the similarities to Super Mario 2. It also sounds like the little cakewalk breakdown in the song “Glory” from the original cast recording of Pippin. It’s just all so familiar without being completely like any of those songs.
Sixty Minute Man gets my vote.
I hear a number of melodies (“Sixty Minute Man” isn’t one of them–this piece is more complicated, and doesn’t have the distinctive progression over (“…fifteen minutes of kissin…'”) in the bridge.
The first thing I thought of was “I’ll Be Down to Get You in a Taxi Honey” (the chorus of “Darktown Strutters Ball”).
I’ll be surprised if it’s a single song.
I’m pretty sure it’s a single song. I even think it’s been sung to, but I have a vague feeling the lyrics have made up words about some mundane thing. Not scat, but like a few nonsense words.
As you think it’s a popular tune from the 30s era I’ve dusted off my Hal Leonard books (gifts I never got around to using). Seeing as I can’t really read music (have to count lines) the going is slow. I can’t just look at the chords because I’m not pitch perfect - I chose C for convenience.

I heard that too.
Part of its sounds like The Beatles “When I’m Sixty four”…particularly “When Im sixty four”
I see now this was already mentioned
It’s just a shot in the dark but I’m getting flashes of old “variety shows” from the late '50s and early '60s where the host, somebody like Perry Como or Andy Williams, sings a duet with a female guest. I’m hearing “Side By Side” or “Darktown Strutters Ball”.
I’m voting for “unrecognizable amalgam” as there are a lot a familiar boogie woogie/stride tropes in there, but it could simply be something obscure. Damn catchy, though.
Will give it some thought.
I’m 95% sure that is a standard called “Frim-Fram Sauce.” 
Here is a slower version from Nat King Cole, and something at your tempo by Diana Krall.
That’s what I was thinking as well. I searched for “Flim-Flam sauce” a couple of days and got nothing, so I gave up.
