On December 30, 1903, during a SRO matinee performance, a spark from a stage light ignites a fire in Chicago's Iroquois Theatre. Of the estimated 2,100+ patrons, players and employees in the building, about 605 are killed and about 250 injured. It is the deadliest theatre fire, and the deadliest single building fire, in US history. Despite claims in brochures that the brand-new Iroquois (its grand opening was just 5 weeks earlier) was "absolutely fireproof", a Chicago Fire captain had found numerous deficiencies in an unofficial tour, but was told it was too late to postpone the opening. The fire brought about numerous developments in fire safety, especially for buildings of public assembly, around the country. On December 30, 1993, anti-abortionist John Salvi III goes on a killing spree, shooting up two abortion clinics in Brookline, Massachusetts. Seven employees in the two clinics are killed. Salvi is captured a day later in Norfolk, VA, after firing 23 shots into a clinic there. Salvi had exhibited a state of mental deterioration for some time before the shootings, but family members refused to seek treatment. At trial, his defense went for an insanity plea; the jury rejected it and convicted him on 2 counts of murder. Given a life sentence, Salvi killed himself in prison in November, 1996. On November 30, 1968, the band Vanilla Fudge is headlining in the Gonzaga University auditorium in Spokane, WA. The opening act is a British quartet performing for just the 5th time in the U.S. Although unknown (their name isn't even spelled correctly on the concert poster), there is interest, rock fans knowing that the new group was built around the former guitarist for the Yardbirds. One concert goer clandestinely records the performance on audio casette (below) in its entirety. It is the first-ever live recording of Led Zeppelin.
