Another show on embattled comedian Bill Cosby's ongoing stand-up tour has been cancelled amid the multiple sexual assault accusations hanging over the funnyman.

Cosby has been forced to scrap a series of concerts as promoters balk at the claims of rape and inappropriate behaviour from more than 20 women, even though he has never been charged with any crime relating to the alleged claims.

Now, a March (15) date at the University of Kentucky in Lexington has been postponed "by mutual agreement".

A 12 February (15) show in Bakersfield, California was also postponed, while a 21 February (15) gig at Heinz Hall in Pittsburgh, Pennsylvania was cancelled.

Legal representatives for Cosby have denied the decades-old allegations of sexual assault.
