I cannot get the beat of this song out of my head, despite the bloke y years passed. i remember that the ad started with pedestrians waiting at a traffic light and when it switches to green (and the beat begins playing) they walk like on a catwalk. i have seen this ad numerous times on irish/british tv in 2002 or 2003. thank you for any hint!

Im sexy for my shirt, by the way thats a lame guess.
