For musicians, managers, and venue owners, the fears of a concert going awry are multiple. Often the problem is crowd control (the 11 fans who were stomped to death at the Who concert in Cincinnati in 1979). Sometimes it stems from security (the Hells Angels at the Altamont Speedway in 1969). Other times the issue is the performer (Jim Morrison’s antics at the Dinner Key Auditorium in Miami, 1969). And still other times it’s a combination of factors (the Diana Ross concert in Central Park in 1983 was cancelled the first day because of a severe thunderstorm and concluded the next day with the gang rampage known as “wilding”). But a concert ending because of pigeon droppings? This has to be a first.
