This afternoon, it finally arrived. Last summer I read about the upcoming release of “Trouble Boys,” the first definitive, authorized biography of the Replacements, scheduled for December publication. Lauren ordered it for me, but then we learned it had been pushed to March 1. And here it is, more than 400 pages, evidently very well researched and written — much more than a fan book, but a bonafide honest-to-goodness biography. I still have more than 100 pages to read in my current book, which I’m enjoying. It will be all I can do not to ditch it and dive into this one.
