James and the team reunite a teenage rock band, now middle-aged, and gets them to play their first concert in 20 years - in front of 5,000 unsuspecting festival goers. James also demonstrates his own axe skills as he fells a tree, makes toilet paper out of Richard Hammond's autobiography and learns how to tame his fears by going on a good old-fashioned ghost hunt in one of Britain's most haunted castles.
