Name the tune

[bonanova]

It's Saturday night and being a puzzle writer I have no social life.
So I make a list of a dozen things:

a conference
a multiplier
a musical instrument
a person who celebrates a holiday twice
a superlative
means of communicating
some clothes
some fibers
some names
someone who hides
two maladies

I lazily let my pencil wander down through the list, twice, thus dividing each word into three pieces of lengths 1, 2, 3, 4 and 6:

E E T [3]

AD ES ES ES FI MA MO OW PO RS SA WW [11]

AYS CRI CZE GRA LAN NDD OLD ROU STO VEF WAR WAW XOP [14]

DROB GHAG GUAG HONE NIKE STOM SPES [7]

ACHACH [1]

Finally, I notice that if I take the 2nd letter of each word, I get some music that tabby might sing.

Name the tune.

Which gives me OIARRAAOOTTC.

I'm not really noticing anything other than the fact that there are a heck of a lot of double letter pairs[/spoiler]

Is it A Cat Oratorio?

Is it Fiiiiiigaro? Not really an oratorio, though.
