That's one that might come up again, so I'm going to post the lyrics so they'll turn up in our search engine. Not folk, but close enough. From this link posted above. I guess I remember this recording, but I wonder if the "my name is Michael" might come from something earlier.

Playground In My Mind
Clint Holmes

When this old world gets me down
And there's no love to be found
I close my eyes and soon I find
I'm in a playground in my mind
Where the children laugh and the children play
And we sing a song all day

"My name is Michael, I got a nickel
I got a nickel, shiny and new
I'm gonna buy me all kinds of candy
That's what I'm gonna do"

See the little children
Living in a world that I left behind
Happy little children
In the playround in my mind

Oh the wonders that I find
In the playground in my mind
In a world that used to be
Close your eyes and follow me
Where the children laugh and the children play
And we sing a song all day

"My girl is Cindy
When we get married, we're gonna have a baby or two
We're gonna let them visit their grandma
That's what we're gonna do"

"My name is Cindy
When we get married, were gonna have a baby or two
We're gonna let them vist their grandma
That's what we're gonna do"

See the little children
See how they're playing so happy
In the playround in my mind

Ba ba ba ba ba ba ba
La la la la la la la
