OK, there has been this ad on TV in the last few months (I think I saw it a few times in July/August), in which a silver car is driving on darkened roads. The colours are all black, white and shades of dark blue. Whenever there is a camera shot while the man is driving the car, there is this music playing sounding like a young boy or girl singing in a high voice. There is no heavy beat or anyhing like that, the music is very quiet and peaceful. As soon as the man gets out of the car, a load of people appear, the music stops and you can hear the noise of the crowd. The man gets back in the car, shuts the door and drives away and the music starts again. Anyone know what that music is? I think it's an ad for a Lexus but I can't remember and haven't seen the ad lately. Help much appreciated.
