Test your dancefloor stamina in an eight-hour dance marathon to raise funds for brain injury charity Headway East London. The event is great fun and there\'ll be live bands, games, cabaret and competitions throughout the day to keep your energy levels up. Each hour there\'s a different musical theme, moving from the 1940s (with guests Swing Patrol) to the present day, via rock \'n\' roll, funk, disco and hip hop. You will need to raise sponsorship of £250 to take part.
