The advert was on a few years ago and featured a very classy young French woman (not Nicole & Papa) in a very sleek house. The music was by a jazz organist, quite groovy, with Hammond organ and electric guitar. Who was the artist?
The tune is Organ Grinder's Swing by Jimmy Smith. It's available on Jimmy Smith's "best of" album, JS:B-3 (and probably others, should a 28-track double CD be a bit much!)
