In comedy, there are knowns and there are known unknowns. For example, you know that Jeff Innocent and Dana Alexander are going to put on one hell of a show at Heaven. You also know that MC Russell Hicks will form the comedic lubricant that ensures the night runs smoothly. But what about the ‘special guest who can’t be named’? It’s a known unknown. Over 14s only, under 16s with an adult.
