Analysis of The Rat-Catcher

I AM the bard known far and wide,
The travell'd rat-catcher beside;
A man most needful to this town,
So glorious through its old renown.
However many rats I see,
How many weasels there may be,
I cleanse the place from ev'ry one,
All needs must helter-skelter run.

Sometimes the bard so full of cheer
As a child-catcher will appear,
Who e'en the wildest captive brings,
Whene'er his golden tales he sings.
However proud each boy in heart,
However much the maidens start,
I bid the chords sweet music make,
And all must follow in my wake.

Sometimes the skillful bard ye view
In the form of maiden-catcher too;
For he no city enters e'er,
Without effecting wonders there.
However coy may be each maid,
However the women seem afraid,
Yet all will love-sick be ere long
To sound of magic lute and song.
