In Spring, this girl's heart goes a-pitter patter for a good patter song -

Advent of Spring

Under the beechful eye,
When causeless brandslings bring,
Let the froddering crooner cry,
And the braddled sapster sing.
For never and never again
Will the tottering bauble bray,
For bratticed wrackers are singing aloud,
And the throngers croon in May!

The wracking globe unstrung,
Unstrung in the frittering light
Of a moon that knows no day!
Of a day that knows no night!
Diving away in the crowd
Of sparkling frets of spray
The bratticed wrackers are singing aloud,
And the throngers croon in May!

Hasten, O hapful blue,
Blue of the thimmering brow,
Hasten to meet your crew,
Theyll clamour to pelt thee now!
For never again shall a cloud
Out-thribble the babbling day,
When bratticed wrackers are singing aloud,
And the throngers croon in May!

-W. S. Gilbert, from the Bab Ballads.

From what I've read so far in a book I picked up the other day, the Bab Ballads are considered to be Sullivan's major work. The edition that I have contains the full collection of songs accompanied by his wonderfully farfelu drawings. All of it is a bit redolent of Edward Lear.
