This series sees Sir Lenny Henry, Chris McCausland, James May and Chris Packham don their walking boots as they accompany Alexander in the great outdoors to amble from one lovely pub to the next in Yorkshire, Kent, Monmouthshire and Shropshire. Along the way, they take in the landscapes, nature and history, as well as sharing wide-ranging, funny and sometimes very personal conversations.

Perfect Pub Walks sees comedian, musician and nature-lover Bill Bailey set out on some of the best and most spectacular pub walks the country has to offer, taking in the Peak District, Somerset, Dorset, Essex and Suffolk.

In each of the four episodes Bill is accompanied by a different guest - Alan Davies, Sir Trevor McDonald, Paul Merton and legendary Happy Mondays frontman Shaun Ryder - and together they share wide-ranging, funny and sometimes very personal conversations, on their way to a variety of historic pubs.

Covering everything from nature and history to music, food and art, their talks will also delve into memories, challenges and difficult life experiences, broaching subjects that men are sometimes reluctant to open up about.
