hello - i've got the answer to your question(i think) and i only stumbled on this whilst browsing for a different question on the advert.
i've been listening to "Nathaniel Merriweather - Music to make love to your old lady by" - a brilliant trip-hop album with collaborations from Damon Albarn and dan the automator and so on. there's a sexy track on it called "to catch a thief" with vocals from vocalist from fields of the nepheliumumum or something (do an amazon serch for the album for details). drop me a line and i'll send you the mp3.
BUT can you answer this question - WHO is the Lady in the advert??? (and does she want to marry me)
