What is the name of the Bach music played in Top Gear season 13 episode 2 at 07m 38s?

What is the name of the Bach music that James May played in Top Gear season 13 episode 2 at 07m 38s? It's just as he's explaining that he'd done things properly and spent his �300 on what every 17 year old wants......"a bangin' stereo for me tunes", then he plays a piece of Bach on the stereo. There is a clip of the music at http://forums.finalgear.com/top-gear-episode-songs-season-13/13x02-june-28th-2009-a-36985/ but no name!! Help me someone...please!
