Short answer is, pretty often. I think Wheeler picked the names he dropped because these folks have had a tendency to do local gigs, small and big scale, to show up on stage from time to time with others, quietly do local benefits or just show up to them, and these people were and are typically welcoming to, supportive of, and respected by other musicians and artists. That's a big part of where the loss is. It's always been the case that artists get pushed out to the 'burbs or small towns, but it's sharper now than ever and it's noticible as aspects of our cities that used to be inspiring disappear. That said, hopefully it's great for Stratford, Guelph, Hamilton, Kingston, etc., in Ontario.
