In our first post lockdown episode, actor and musician Johnny Flynn takes Matthew Bannister for a walk on the Hackney Marshes, a huge expanse of public land which has no fewer than 88 football pitches alongside a nature reserve which has grown up in disused gravel pits. As well as singing his distinctive, haunting songs, Johnny relates his near miss with a bear on the Camino to Santiago, reflects on discovering the music of Bob Dylan as a teenager and talks about his friendship with the nature writer Robert Macfarlane.
