Ryan Adams plays one of Cardinology's weaker moments ("Sink Ships") for his spin around London in a cab. The cabbie reportedly had to make sure he stayed in a straight line so that Ryan wouldn't throw up (he's apparently carsick). Unfortunately, Ryan made it all the way through without tossing his cookies, blowing chow, ralphing, up-chucking.
