I had the 'bright idea' that maybe if I used na existing tune as a template then took it from there it might give me a better understanding of how it all works.

Now I'll probably be lynched for this.
But I took outlandish knight and kinda...tweaked it. Would you say it was a parody, pastiche or something else?

------
Margaret she sits with her i-phone a-tweeting
Ma ba and the lilly ba
When she heard a car with his hi-fi a-booming
On the very first morning of May
 
"Oh I wish that I could ride in that car I hear growling"
And it's ma ba and the lilly ba
"And had that young man's number to text"
On the very first morning of May
 
Well the lady she had these words scarce spoke
And it's ma ba and the lilly ba
When by her street corner the man come a-strutting
On the very first morning of May
 
"Oh strange it is, oh hot young woman"
And it's ma ba and the lilly ba
" I can scarce use my phone since I hear you a-calling
On the very first morning of May"
 
"Go fetch you the card from your father's table
Deliver it unto me
And the fastest car in your father's garage if your able
The keys give unto me"
 
So they've drove off the shiny, black car
And she's turned up the stereo grey
And they crusied till they come to the broad sea shore
Just three hours before it was day
 
"Get out, get out of the car," he says
"And deliver it unto me
For it's six pretty girls I have drowned here
And the seventh one you shall be"
 
"Get out, get out from the car," she says
"And come and kiss me
For if I'm about to die
I want to this my last action to be"
 
So he's got out the car with a sigh
And he's came closer to she
And she shoved him in the middle so small
And tumbled him all down in the sea
 
Sometimes he sank, sometimes he swam
And it's ma ba and the lilly ba
"Oh help, oh help, oh my pretty mistress
Or drowned I shall be"
 
"Lie there, lie there oh you false young man
Lie there instead of me
For I'll call the police to deal with you
And to prison they'll send thee"
