Tomorrow night, the latter-day Fagin's gang that is the Kaiser Chiefs are playing Doncaster, live, for the benefit of Radio One listeners. In order to be at their best for this occasion, they're doing a somewhat hastily-arranged warm-up at Leeds Poly tonight. (Oh, alright, Metropolitan University.) You have to buy a ticket in advance, whereupon a wristband will be slapped on you to ensure you don't get lost. Or tout the tickets, or something.
