Information on Joan Baez’ Redlands years has continued to come in despite 2 1/2 previous columns on the subject, and I am helpless to ignore it. In my defense, I got 20 years of occasional columns out of Frank Zappa’s Cucamonga, Ontario and Pomona years. Also, I write about an angle unexplored before: her 1964 evening concert at University of Redlands. (The afternoon concert at Redlands High was a previous topic.) And so, Baez in Redlands makes up Sunday’s column.
