Radio 2 celebrates the launch of the 2009 Blackpool Illuminations with a live concert starring JLS, Madness, Tony Christie, Paloma Faith, and Pixie Lott. The Illuminations began in 1879 with a display of just eight lamps bathing the Promenade in "artificial sunshine". Over one hundred years later, the annual tourist attraction has grown significantly in scale and ambition with the Switch On now illuminating a six-mile display of lights. Kate Thornton hosts proceedings, while the one-time Blackpool resident, and Radio 2 presenter, Alan Carr flicks the famous switch. And Alan will be hosting his weekly show, Going Out With Alan Carr, live from Blackpool's esplanade. Listen tomorrow from 6.00pm.
