So who was 'moany' in the song 'moany moany'?

Question

and why was she moany

Answer 1

It is indeed called Mony Mony. It was by Tommy James and the Shondells, covered later by Billy Idol. Here's the story behind it:

The band had the music written, but needed a girl's name for the title. They wanted a name no one ever heard before, like "Sloopy" or "Bony Maronie," but couldn't think of anything. Kenny Laguna, a producer who played keyboards and sang with The Shondells, explains:

"We used to do a lot of amphetamines, they were very popular with people trying to succeed, so we'd spend all day and night 'up' making records, and not worrying about getting paid. It was perfect for the record companies, who would supply us with amphetamines. One morning, Tommy looked up and saw the corner of a building, it was the Mutual Of New York, MONY MONY. In those days we had 'Yummy Yummy,' 'Chewy Chewy,' 'Sugar Sugar,' anything that could be like that. Tommy saw that and said 'Mony Mony sounds like a girl's name.' So Tommy went around town and wrote 'Mony Mony' with 13 different people."

Answer 2

The song "Mony Mony" was written by Tommy James. It is a fictious name inspired by a sign seen by James while he was trying to come up with a girl's name for a song he was trying to write. He was trying to come up with a song similar to that of
some other songs of the era.
The name was chosen for it's uniqueness but not because he was thinking of a girl that moans a lot.

People who work for the Mutual of New York Insurance Company--also known as M.O.N.Y.--can’t imagine that the staid, conservative company would have anything to do with rock ‘n’ roll. They think it’s just a coincidence that the name of their company is also the title of this song. It isn’t. M.O.N.Y's central office in New York City is a 40-story building located at 1740 Broadway; on top is a huge old sign that flashes the company’s name in neon at night. That sign inspired Tommy James' 1968 hit when he turned it into a girl's name during a songwriting session.

JAMES: "The night we wrote the song, we were absolutely devastated because we couldn’t come up with a 'Bony Moronie,' a 'Sloopy' kind of title, and we knew that’s what it had to be. It had to be a girl's name that nobody had ever heard of before. We were going through the dictionary, but nothing was happening. We were just absolutely frustrated. I walked out onto my terrace--I lived in Manhattan at the time--and I’m just sort of scanning around and I’m looking for just any part of a name, anything. I’m just kind of staring out into space and all of a sudden, I look up and I see [what I’m looking for]. . .I said [to my manager], 'Ritchie, c’mere.' He came over and I said, 'Look.' And all of a sudden, here’s this 'M.O.N.Y' with a dollar sign in the middle of the 'O.' The song kind of etched in stone in New York, I guess. We both just fell down laughing."

Answer 3

"Mony Mony": the name was sheer, dumb luck, a result of Tommy James spotting the Mutual of New York (MONY) illuminated sign atop their building in mid-town Manhattan at a key moment in the creative process."

Answer 4

It's called "Mony Mony."
