The Life & Times of Mad Jack. Marillion's Mark Kelly has had six decades to consider a life less ordinary and the decisions he made that took him there. From a dirt poor childhood in Ireland to some of the biggest stages around the world, Kelly's journey has described an arc that any fiction writer might blanch at. The departure from the band of their singer at the height of their powers; reinventing the music industry wheel by pioneering crowdfunding to help his band survive; and going from club shows to arenas and almonst all the way back again.
