Mark Watson's 24 Hour Jamboree To Save The Planet

The fourth, stamina-testingly long show that Mark Watson has hosted at the Fringe is not so much a gig as an experience. In previous years, the show has remained pretty stationery. This year it is a roving 'jamboree', taking in the sights and sounds of Edinburgh centre at night, the cramped, sweaty enclaves of The Stand Comedy Club, a bus, a field, an obstacle course in a park, a book shop and finally winding up in the festival atmosphere of C Soco's white marquee. 86 people doggedly follow Mark every step of the way, from the first, nervous gathering on the Royal Mile at 11.30pm on Tuesday, to the final, exuberant encore of the house band in the marquee, at midnight the next day. We are left with a feeling of collective achievement unlike any I've had before. Amazingly, we are also kept amused and engaged for almost the entire time. A combination of tiredness and possible repetitive strain injury mean that by the end of the day, my facial muscles are actually frozen uncomfortably into a happy, proud and mildly bewildered grin.

There is no room to go in to any detail in a short review, and (shameless plug) you can read full details of our exploits on the Fest blog, which I kept updated via text-mesage throughout the entire, masochistically enjoyable ordeal. Suffice it to say, here, that it was just a fantastic way to spend a day in the life of our planet.
