COLLECTED

I saw her once
read at the Guggeheim
Ashbery to the side
inclined on a palm

Marianne Moore attended
by her man in livery
& Robert Lowell cleared
his throat introducing

Bill B. was there
already impressed
but I don't recall
her voice or

a line it stressed
and Liz Bishop
is a sportscaster
on the Albany tube

--Clark Coolidge

What is this poem trying to say? Why is Ashbery just "Ashbery" and "Marianne Moore" and "Robert Lowell" get their full names (and Bill Berkson is "Bill B.")? Is it a commentary on literary politics? It isn't exactly pro-Elizabeth Bishop, or anti-Elizabeth Bishop either.
