Harold Oblong was the stage name briefly used by actor and comedic writer Peter Elbling as a choreographer: http://www.phantomoftheparadise.ca/elbling.html
("Oblong" being loosely derived from "Elbling" a name which anecdotally, many people seem to have trouble with, mispronouncing it as either "Elbing" or "Ebling")
"Peter Elbling is better known to fans of Phantom of the Paradise under his stage name Harold Oblong. In the film, he was a member of fictional bands The Juicy Fruits, The Beach Bums and The Undead, and performed the show-stopping lead on "Somebody Super Like You". He's also credited as Phantom's choreographer."
Elbling eventually reverted to the use of his real name.
Legal name: Peter Elbling
