Definitely one of the Great Performances in All Things Rockin', we see here two enormous talents now gone from us and sorely missed...the late greats Phil Lynott and Gary Moore. This performance, on the steps of The Sydney Opera House in Sydney, Australia from 1978, Is a stunning example of a truly great rock unit led by an uncommonly charismatic front man. The first part is "Cowboy Song", one of Thin Lizzy's underappreciated gems. As to the second part, "The Boys Are Back In Town" is Lizzy's signature song. Highly regarded author of some of the best books about rock music ever written, David Thompson said in his book I Hate New Music that "The Boys Are Back In Town" is the last great rock song of the 70s which makes it the last great rock song ever. Hyperbole? Perhaps... but close enough to the truth for me.
