Are you Dave Gorman?

After a heavy night of tequila, flatmates Dave and Danny set off on what turns out to be a 24,000-mile journey to meet all the other Dave Gormans in the world.

They visit Scotland, Israel, America, France and Ireland.

They even hold a party in London where 50 Dave Gormans attend, including two women who have kindly changed their name via deed-poll.

Silly, but engrossing, fascinating and addictive - and a touching story of two friends who grow to share a mutual obsession.
