Recently my small child has been taught Miss Polly Had A Dolly by Grandma. Some of the words are remembered, but not all of them, and I am expected to sing the song.
A search of Google brings up a number of version of the lyrics, mostly differing on what the doctor does, as well as sheet music and CDs with the song on it. Unfortunately finding the song as a sound file is another thing.
So where at 11:30pm do you find a song for a small child who is not sleepy?
iTunes music store it turns out. If you search for “Miss Polly” there are 33 listed songs. Two of the listed songs are pop music, with the rest being the nursery rhyme. So it is quite a popular song to record it seems. Ok, some of those listed are the same recording on different albums, but still quite a big list. And I was interested to find amongst the list an RnB version of the rhyme.
One of the better versions: 
The RnB version:
Included below are lyrics familiar to me.
Miss Polly had a dolly
Who was sick, sick, sick,
So she called for the doctor
To be quick, quick, quick;
The doctor came
With his bag and his hat,
And he knocked at the door
With a rat-a-tat-tat.
He looked at the dolly
And he shook his head,
And he said “Miss Polly,
Put her straight to bed.”
He wrote out a paper
For a pill, pill, pill,
“I’ll be back in the morning
With the bill, bill, bill.”
We thort polly’s dolly’s head falls off.
