New comedy from Gruff Rhys (pictured). In this programme, Gruff will attempt to understand crowd behaviour in order to free the audience from the tyranny of the artist, and free all people from all leaders.

Gruff begins his quest with a pilgrimage to a phone box in Bangor, where The Beatles heard of Brian Epstein's death, and in which he used to sleep.

Once he finds the phone box, Gruff will call his guests: Professor of Social Psychology Stephen Reicher, and psychologist and author Dr Jenny Boyd, who was there on that legendary trip to Bangor in 1967 with The Beatles, Marianne Faithfull, The Rolling Stones and the Maharishi.

Through the lens of Beatlemania and pop culture, Gruff and his guests will attempt to answer important questions such as: do we really get a sense of wellbeing when we share time and space with others, when we are part of a group or an audience? What happens when the crowd turns? And why does it take five trains to go from Cardiff to Bangor?
