More counterfactual history from a document in the GD Archives (ms332, ser2, box5), though I have seen it through another means as well.
This is a central piece of evidence, along with the Return of Ronnie Tutt tour in late '81 and a few other things, showing that this period marks a real effort to take care of old business. This especially involved disentangling Jerry/JGB and Grateful Dead finances. Though Marin County documents didn't yield any tax liens and such in this period that I could find (unlike 1978), Jerry was definitely having tax and more general money issues around this time, and this tour-that-wasn't, forecast from ca. February 1982, figured centrally in the various planning. (The fact that it didn't happen this way only speaks to the difficulties of taking care of business!)
