Born Joan Molinsky in 1933, Joan Rivers shot to fame on The Tonight Show with Johnny Carson, who she later infuriated by hosting a late night chat show of her own. Comedian and writer Helen Lederer, author of Not That I Am Bitter, picks Joan for her fearless ability to take on the men, particularly those who interviewed her.

"In 1984 I went to see an Audience with Joan Rivers, and she was like this angel with blonde hair and glitter ... with gags, with content, ferocious, aggressive, intelligent."

Joining the discussion from New York is the critic Joe Queenan, twice a guest on Joan Rivers' show. "She told the audience in no uncertain terms, you better laugh at everything he says. She radiated this affection, she was great."

Presented by Kirsty Lang and produced in Bristol by Miles Warde for BBC Studios.
