Theodoric..."recital" = term for a performance of a dance/singing group.
"Mister Mistoffelees" = one of the most famous songs from CATS, Broadway musical based on poems from TS Eliot and that is the way it is spelled in the play.
It was a local theatre, so instead of full out cat costumes like the original show, the back up girls ('cat chorus') went with being "nekomimis" and we had cosplay pieces from Japan. Ribboned ears, bells, tails, nyan paws.
Nothing more, nothing sinister or no double meanings and nothing to hide. Just fun stuff.
My inspiration was Anna Marie, so my accessories were all pink. Come to think of it, we looked like we were all doing the "Nyan Nyan" dance. ROTFL.
