Legendary folk rock singer Janis Ian, who was 16 when she released the 1966 civil rights hit "Society's Child," says she has a personal stake in the sexual accusations against Bill Cosby.

Janis Ian took to Facebook to recount an incident that happened when she was "The Smothers Brothers Comedy Hour."

"No, I was not sexually bothered by Bill Cosby," said Ian in a Facebook post Tuesday.

According to the Facebook post, Ian was exhausted from press coverage and fell asleep on the lap a woman chaperone who six or seven years older than Ian. When the singer got home from the performance her manager called her to say "no one else on TV is willing to have you on."

Bill Cosby saw Ian asleep in the woman's lap and blacklisted the singer, telling other shows she wasn't "suitable family entertainment" because she "was probably a lesbian, and shouldn't be on television."

Ian said that Cosby showed up in the studio to meet her.

"We met because he was curious about me," wrote Ian.

"Remember. I was sixteen. Still in high school. Fairly naive, including about my own sexuality," Ian wrote. "For months on the road, my chaperone was the only consistent face I saw. Everyone else was a complete stranger -- radio personalities, newspaper reporters, magazine photographers, audiences, promoters, disc jockeys, all strangers. So I clung to my chaperone."

"Again, a reminder. I was 16. I'd never slept with a man, I'd never slept with a woman. Hell, I barely been kissed, and that in the middle of the summer camp sports area, next to the ping pong table."

"[I] was told that Cosby, seeing me asleep in the chaperone's lap, had made it his business to 'warn' other shows that I wasn't 'suitable family entertainment,' was probably a lesbian, and shouldn't be on television," Ian wrote.

Bill Cosby is dodging dozens of allegations that he drugged and raped women from the 1960s to the 1990s.

"There's a lot to bother a sensible person about this," Ian continued. "The years these women were ignored. The years they were derided. That the story finally really 'broke' because a male comedian named Hannibal Buress kept bringing it up, kept calling Cosby a 'rapist.' Not because woman after woman after woman went to the police, to the press, to anyone who'd listen, with horribly similar stories."

In spite of the blacklist, Ian was still booked on Johnny Carson's Tonight Show.

"Cosby was right in one thing. I am gay. Or bi, if you prefer, since I dearly loved the two men I lived with over the years. My tilt is toward women, though, and he was right about that," Ian added.
