Switching banks had always been a hassle, until CASS came along and made the banks do all the work. So I showed everyone just how smooth a switch can be by creating Switch Guarantee Guy – a slick-singing, smooth-moving star with all the charisma of 70s superhero Shaft. I suited him up (in a custom-made Vivienne Westwood no less), and then got Oscar-nominee Peter Cattaneo to capture all the action as SGG serenaded the high street.
