In what sounds like the making of a comedy gag - an Irish man, an English man and a Northerner, otherwise known as Dara O'Briain, Jack Whitehall and Jon Richardson will be taking to the skies to perform a special stand-up gig. The trio will be attempting to set a new Guinness World Records title for the 'Highest Stand-Up Comedy Gig in the World' on Saturday 12 March 2011, in support of this year's Red Nose Day.
