Emily Benson Tickets are now on sale for comedy fundraiser Weston Park Cancer Charity's ‘Funny Business' comedy challenge is making a comeback after an eight-year hiatus. In the fundraiser, thrill-seeking supporters will develop their very own stand-up routine, which they'll perform in Sheffield City Hall's Memorial Hall on Thursday, November 12. Contestants will be taught the tricks of the trade in group coaching sessions, under the guidance of professional comedian, Colin Manford.
