Billy Connolly - raconteur, comedian, and irrepressible wanderer - has spent much of his life in the United States.
It's a country he knows and loves a great deal, but even someone as well-travelled as Billy can always discover knew things about such a vast nation.
So he's off on the move again, this time via the tracks of the great railroads that helped to build the country. Billy's latest adventure takes him on an epic trip through the backyard of America, tracing the routes taken by the first European settlers westwards from Chicago to California, then back down south and eastwards through Arizona, Texas, Alabama and finally New York, over 6,000 miles and 26 states later.
It's a journey through a country you don't get to see from 30,000 feet in the air - the real America of friendly people with fascinating tales to tell which not only give us an insight into their lives, but also into the life of their great homeland. And it's a journey that couldn't be shared with a more entertaining companion.
Hope aboard and join Billy on a trip you'll never forget.
