Surprisingly, Bob Dylan first came to the attention of the British public through his role in a 1963 BBC TV play, The Madhouse on Castle Street. The tape was later wiped and has since become the holy grail of missing Dylan works. Joining the hunt, Arena uncovers rare Dylan tracks and the fascinating story of his first time in London. Featuring writer Evan Jones, director Philip Saville, and fellow musicians Martin Carthy and Peggy Seeger.
