For this final grand tour Paul is heading as far north as you can go in Britain, to the islands of Fetlar, Unst and Yell. These islands, which lie on Scotland's northern frontier, are as much Scandinavian as Scottish and were in fact once part of Norway. Along the way he will sing with the Shanty Yell Men who came together to celebrate their Norse heritage, learn how to 'roo' Shetland sheep the traditional way, and get an incredible opportunity to see up close the wild otters who make their home here in Shetland's pristine waters. And finally, Paul will fulfil a long-held ambition to visit Out Stack, the rocky outcrop that is famous for being the 'full stop' at the edge of Britain.
