Broadcaster Marc Riley, rock musician Damon Albarn and film maker Ceri Levy venture outside their usual comfort zone and travel to Mull in search of Sea Eagles and Basking Sharks.
During their weekend on the island they do some bird watching, swim with seals and Damon composes a new piece of music which he performs to Marc and Ceri in Fingal's cave on the Isle of Staffa, using the unique echoes of the waves in the cave as accompaniment.
During their journey they discuss Gilbert and Sullivan, how to catch a Blue Tit in a snowy garden and the reintroduction of Sea Eagles to the Scottish Islands.
As a finale to the weekend, Marc and Damon overcome their fears and venture into the deep waters off Mull to swim with Basking Sharks, some of them over 20 feet in length.
