I also got for Xmess a book, I don't have it with me at the moment, its name is something like
Queers in History and is like an encyclopedia of everyone even suspected of having had sex with a member of their own gender.
One tale I found particularly fascinating because it involved King Elvis.
According to the author, Elvis's Stepmother, Dee Presley, seen here with Elvis' father, Vernon,
wrote an unpublished biograph of the King in which she maintained he was bisexual and had an affair in his Hollywood days with the actor Nick Adams.
She also maintained that Elvis's agent, Col. Tom Parker, knew about his sexuality and used this knowledge to blackmail the king into doing more schmaltzy movies. I dunno, I have looked for independent confirmation of this and no one seems to be as convinced as this text I got for Xmess. Here is what Wikipedia sez about Nick Adams
