Evil host Adam Hills is king of the castle - the castle being his own music quiz show. Ready to fight him are team captains: the ever gallant 'knight in shining armour' Myf Warhurst and the 'damsel in distress' Alan Brough. Fellow knights of the round table are the 'clumsy Sir Lancelot' comedian Colin Lane, 'serving wench' singer Renee Geyer, and dragon-in-training singer Paul Capsis.
