In November 1977, when Thin Lizzy performed at the Sydney Opera House, the band was riding high on the success of their album "Jailbreak," released earlier that year. This album marked a significant point in their career, featuring hits like "The Boys Are Back in Town" and showcasing their blend of hard rock and melodic undertones, which would come to define their sound. The live performance of "Waiting for an Alibi" captures the band's dynamic energy during this peak period, with Phil Lynott's charismatic stage presence and dual guitar harmonies from Scott Gorham and Gary Moore prominently on display. Notably, the lineup at this concert included the legendary Gary Moore, who briefly joined the band, adding depth to their guitar work and contributing to their music's evolution in the late 1970s. Thin Lizzy was not just performing; they were solidifying their place in rock history during this iconic live session.
