Here is a clip of Judy Collins singing at the Joe Hill commemoration concert in Salt Lake City over Labor Day weekend: https://www.youtube.com/watch?v=GONWYQJ4Q0g
We’re looking for a report on the event; the local daily seems to have been content to run a photo on its website early in the day. However, they have posted a package on the Joe Hill centenary which gives a reasonably good overview — except that it ignores the strong evidence William Adler’s book presents that Joe Hill was innocent, and that police let the actual murderer go in order to pursue their frame-up. Instead, the paper gives space to the family of the murdered grocer to assert that no amount of evidence can move them to recognize the truth. To make up for it, there’s a pretty good short graphic novel treatment of Joe Hill’s life.
