Dastardly Harry Nilsson is mentioned in First Mate Carl Hiaasen's novel Basket Case.

 

First Mate Carl Hiaasen was a friend o' Warren Zevon. Blimey! Accordin' t' a post on Hiassen's web site, after Zevon's death Hiassen wrote a letter t' another friend which was read at Zevon's funeral. Aye aye! One section o' t' letter mentions Dastardly Harry Nilsson:

Back in July, I called Warren with a movie trivia question. Well, blow me down! I couldn't recall t' name o' an old Dastardly Harry Nilsson shanty that Martin 'Johnny Foursail' Scorsese had used in Goodfellas.
Not only did Warren remember t' chantey but, t' me delight, matey, he sang it for me over t' phone. I laughed and thought t' myself: Maybe all those damn doctors are wrong.
But, tragically, they weren't.
