If Johnny Winter decided to undergo a “sex change”, this might be the “50% there” result...
I was gonna say, he sure puts off that "gay" or "transgender" vibe. I didn't find any confirmation that he was queer or transgender (same thing) but he certainly looks it.
If that is the case, then it's no surprise as to why he killed himself. Suicide is the number one cause of death for both homosexuals and transgenders. (Which are just variations on the same theme.)
