DECEMBER 17, 1977 – One of the defining moments in Elvis Costello’s career happened when he appeared on “Saturday Night Live”. The Sex Pistols, who were booked to perform, were denied entry into the US based on various band members’ criminal records and “moral turpitude” and Costello was booked to fill in. Costello was 23 years old. His debut album “My Aim Is True” had just come out in America a month earlier. When the Sex Pistols were unable to appear on the show as planned. Costello and his recently formed band, the Attractions, got their big break.
