Elvis Costello at Debut of 'Spectacle: Elvis Costello with ' at Edison Ballroom - arrivals. New York City, USA - 061108

Hess maintains the name of his socially-challenged film character was something he dreamed up - but Costello disputes this.

Costello tells America's Spin magazine, "The guy just denies completely that I made the name up... but I invented it.

"Maybe somebody told him the name and he truly feels that he came about it by chance. But it's two words that you're never going to hear together."
