Community Center Arena, Tucson, AZ
Opened for Santana. A poster has circulated showing that Santana/Weather Report were in El Paso on Dec. 14 and Tucson on Dec. 15, but the Tuscon show was clearly on Dec. 14 as evidence by newspaper advertisements and a review of the show, which appeared in the Tucson Daily Citizen on Dec. 15. I have no information confirmation of an El Paso show.
