I have the original book (1966, first edition). I found out about it from a Time magazine review, in which the reviewer wrote:
Higglety-pigglety
Anthony/Hollander
Two poetasters who
Write with one hand
Soon they must issue
New co-miscellania
If they’re to live off
The fad of the land.
And, being music-oriented, I must repeat a related verse:
Higglety-piggledy
Ludwig van Beethoven
Bored by requests for some
Music to hum,
Finally answered with
Oversimplicity,
“Here’s my fifth Symphony:
Duh, duh, duh, DUM!”
