Firstly, remember the clocks go forward one hour at 1am this saturday night. Showtime on air at 3.30am, so the fight should start about 3.45. But obviously, it's an hour earlier GMT so if you don't change your clocks till you wake up on sunday, it starts at 2.30. Confusing, but it won't be too late a start, even if 3.45 looks late at first glance.
Good point, thanks for the reminder about the clocks. Had to think about your explanation for a minute there. Must be tired
