The Nassau Veterans Memorial Coliseum had done its duty. Opened in 1972 in Uniondale, N.Y., the Coliseum not only had honored the military sacrifice of local veterans in Long Island’s Nassau County but had served as home to the one-time American Basketball Association’s New York Nets and the National Hockey League’s New York Islanders as well as hosted major events and concerts, including performances by Elvis Presley, Madonna and Bruce Springsteen.
