Help! Bridgestone ad!

Help! That new Bridgestone tyres advertisement jingle is stuck in my head! The one that shows a car driving down a long and winding road, and starts with “On and on …”.

Is that a real song? Or is it just an ad jingle? If it is a real song, can anyone tell me what the song is, who sang it, where are the lyrics, what CD is it on and is there an MP3 available?

Help, that thing is stuck in my head and won’t let go!
