We had a 45 of it at a radio station where I used to work. The label read “The Manna Manna Song” by “The Muppets”.
They did the song on the short-lived Muppets Tonight. Sandra Bullock was the guest host, and they did a skit with her and (as I recall) Kermit as psychiatrist and patient, respectively. The Snowths (that’s what those pink cow-like things are called) popped out and "doo dooooo, doo doo doo"ed every time one of them said “phenomenon”.
Oh, aren’t you a sweet young thing. Us old folks remember it from Seseme Street.
I sing it in funny voices for my kids.
Are these the same guys who did Popcorn? 'Cause I love that song.

Sorry, Paul, I found the idea of it humorous, but not knowing the real anthem, I don’t know how appropriate it is as a parody of the actual music.
Besides, every one who’s been through introductory chemistry knows it’s not “Mahna Mahna.” It’s “Manometer.” 
Actually, us old folks remember it from the Ed Sullivan and Red Skelton shows.
I know that girl! Her name is Annie Gronbeck-Tedesco (possibly just Annie Tedesco as her professional name). I went to college with her!
Many, many of my friends went to high school with her.
She was also in a no-budget movie I worked on called “Small Secrets”.
That is, the girl in the Dr. Pepper commercial.
Irn Bru. It’s Phenomenal.

Hey, now I am 34. It’s entirely possible I don’t remember it on Sesame Street because I swore off the show after Mr. Hooper’s death and was busy outside riding my Green Machine from the 7-11, wearing my Zips, eating Pop Rocks (10 cents) and Now or Laters (10 cents) and a Watchamacallit (15 cents) for 35 cents.
I got it 
Whoa, that was my life at the time too! Except I had my Green Machine stolen at the school playground and I was down at Rogers’ Pantry looking for new Garbage Pail kids:) I’m 35, btw.
Psst: Yep.
I love it, too. I don’t know much about it, just that my father told me as a very impressionable child that it came out in the 70s and was the first song made entirely by synthesizers to make it on the charts. He bought me a moog shortly afterward, and they were very expensive back then…
The only thing about this story that is a fact are the personal details. The rest I’ll have to look up.

*Popcorn * is also the title of the album. Glued on the cover is a flattened popcorn box. I’m pretty sure it’s still in my closet with the other few hundred albums I’m in custody of from my parents and brother.
sniff I never had a Green Machine, I had to make do with a series of big wheels. I kept wearing out the front tire, would rub right through the center of it.
Okay, I’ll abase myself and admit to not getting it, but now you have to explain it.
I’ll be checking in on Monday.
The capital of Bahrain is …
I remember the OP’s very question being used on Jeopardy once. It was the Audio Daily Double in the Stupid Answers category (no offense to the OP!).
