Not to fuel an argument, but He was self-admittedly an "odd duck" and he did not hide this from the media. Part of it was his Shtick (or however you spell it) but even in an interview with him and his wife before they got married, Miss Vicki stated that they were to have separate bedrooms, bathrooms, and would not be eating together. He did not like for people to see him eat. He was also known to be OCD and showering often. In describing their courtship, after they first held hands he then applied cold cream to both their hands for cleanliness reasons. I am not sure about all the odd sexual stuff, but he definitely had OCD and a few other eccentric habits, some of which seem to have came from his devout religious beliefs. I forget the psych word for it, but basically it is the formation of superstitious behaviors around a need for penance or cleanliness and what-not. But that is just my opinion. Not from an article. It just seemed like a lot of things he did was to avoid being unclean (particularly sexually). There are many psychological things I can infer from some of the behavior, but that would be my opinion from what I have read. It just seems like he was a guy who was insecure with himself, and his looks, and he found an interesting way to make his mark in the world. Truly an interesting character and it is amazing he achieved the fame he did. Basically he sings a lot of old-school for his time songs, just in a weird voice. But he has quite a magic voice. He can really tailor it to fit what he is singing. Basically, he is like the weird-Al of his time, just without the social skills... he did not change words to pop songs, but he made old songs (for his time) "new" with his unique style. Tiptoe through the Tulips was origionally recorded in 1926 by a crooner.
Maybe this is morbid of me, but I find it cool how he died, on stage singing his hit song. His wife at the time said when he died the last thing he heard was applause and the last thing he felt is her arms around him. The kind of ending a screenwriter would write. His life might make for an interesting movie.
