The Blues Brothers themselves are two brothers, "Joliet" Jake and Elwood, who scour the city of Chicago, reuniting their band members, to raise money for the orphanage in which the two grew up. Jake is also being relentlessly pursued by his enurotic and sociopathic ex-fiancee, played by Carrie Fisher ((AKA Princess Leia)). Dan Aykroyd and John Belushi, who portray the two brothers, do all their own singing and dancing. Dan Aykroyd designed the Bluesmobile.
