The Titter Sisters are a mid-20th century comic duo playing the clubs. They can't stand one another. A dark comedy - tantalisingly acerbic, witty and macabre, exploring the curse of being the eternal stooge.

Miranda Richardson plays dark comedy monster and genius Joy. Jessica Gunning is Jane - the stooge with hate in her heart, revenge on her mind and a total sense of humour bypass.

The drama marks a welcome return to Radio 4 for star comedy writer Georgia Pritchett, who says, "The play is an investigation, and also a celebration, of comedy, comedians, double acts and jokes."
