I was surfing around YouTube.com when I finally found it.
It also listed as manamana. However, I had always thought it was "monomonop." And sung it that way, too.
Whatever it's called, I'm sure I drove my family nuts as I sang it all the way as we drove from the family home in Hicksville (now, come on, where else would I be from?), Long Island to Florida.
From the show, "Sesame Street," "Mahna Manha" was a simple song sung by two girl muppets, who sang "ba-dee-ba-dee-bee" and one heavily bearded muppet who would exasperate his co-singers as he frequently embellished his "mahna mahna" part.
I've had this song stuck in my head for several days now. So, I just figured I'd share.
