"John Mann, lead singer for Vancouver-based folk veterans Spirit of the West, revealed this week he has been suffering from early-onset Alzheimer's disease. He is 51. The band's other members simultaneously released a statement indicating they intend to continue performing with Mann in the face of his diagnosis. Geoffrey Kelly is John Mann's long time collaborator -- having co-founded Spirit of the West with him in the early '80s."
