I still watch Top Gear even though it is wearing a bit thin now (stupid big oaf laughs at the small clever one's jokes and in turn both take the **** out of the sad slow quiet one whilst on a blatantly staged 'challenge'.) Still, a well put together and watchable show.
Good website I found whilst trying to work out some of the tunes they use in episodes -
