A Walk Around Britain - Short Version from awalkaroundbritain on Vimeo.
Here's what the Guardian.co.uk has to say:
Three young men having been walking across Britain without any money, camping out and relying on the kindness of strangers to survive. Calling themselves "singing adventurers", they have taken three major trips in the past three years, sleeping wherever they can and foraging for food. They sing three-part folk songs, ancient and modern, wherever they are welcomed. They "busk in heaving towns, chant in crumbling chapels, and get feet tapping in many a-pub across the land."
Here's their website and it's got some of their songs on it. Beautiful!!!
