I have just discovered something: William McGonagle and Julia Moore were very likely the parents of rap!

E.g., read this pausing at the //:

Alas! // the people now do sigh and moan
For the loss of Wm. // Ewart Gladstone, //
Who was a very great politician // and a moral man, //
And to gainsay it // there's few people can.

And, from Ms. Julia (same reading deal):

Come, freeman, // now arise,
Put your shoulder to the wheel //
This Presidential elec // tion;
Vote for an independent man, //
One in favor of greenbacks,
In this great finan //cial question.

Also, ignore the authors' punctuation.
