I can put you out of your misery. I tracked down the agency repsonsible for the ad (in Los Angeles), contacted them and their reply was "The music you like is an original composition that was composed for the commercial. It is unfortunately, not available for purchase".
It does not have a name. it was recorded especially for the advertising agency by Toby Pitman who is a London based session player. As well as session guitar, Toby is also in demand as a Programmer/Producer and has extensive knowledge of studio technology and production techniques as well as being a first call composer/arranger for some of the biggest names in advertising.
