I recall this song very well. I will lay money on the following being the exact lyric:

If you have a nickel,
You can buy a Popsicle.
You can buy it from
The Popsicle man.

You can have any flavor
That you wish or you favor
All you do is ask
The Popsicle man.

As he comes down the street
With his ding-a-ling-a-ling-a-ling,
All the children start running
And then they all begin to sing.

If you have a nickel,
You can buy a Popsicle.
You can buy it from
The Popsicle man.
