✔️1994/03/18 Phoenix, AZ The Roxy - <s>Did the second show happen at The Roxy? NIN Historian originally had The Grind. Some guy on setlist.fm also claims it was The Grind, though his anecdote does not actually provide any evidence to back that up. happinessinheresy's newspaper clipping shows both shows were sold for The Roxy, so if it changed, it was a last-minute venue change.</s> [http://nintourhistory.com/uploads/tickets/154422523288image.jpg Ticket stub] confirms 2nd show was at the Roxy.
1994/03/27 Honolulu, HI After Dark - This was solicited in the newspaper, up to the day before the show, as a single date, Mar. 26, at After Dark. There is a ticket stub and posters for the 26th on nintourhistory/HIH, but nothing for the 27th. Need to talk to Bill Rose, who did security there, about the show(s).
1995/11/11 St. Petersburg, FL Jannus Landing (show went on as planned?) - This is the only date we're not absolutely sure went on as planned.
1995/11/27 Corpus Christi, TX Cantina Santa Fe - This date probably is fake. Contacted JJ Nelson to try to find out.
