A burst of lush sincerity in an age of irony, the Australian rock duo of singer Russell Hitchcock and singer-songwriter and guitarist Graham Russell saturated early ’80s radio with big orchestrations and achingly earnest love songs. But long after their inescapable hits became ironic staples of hammy, besotted karaoke nights, in 2005 Air Supply released The Singer and the Song, an acoustic album that stripped down such chestnuts as “All Out of Love” and “The One that You Love” to their melodic essence. And you know what? It was kind of a revelation. Hitchcock’s voice had shed a layer of melodrama and sugar, and to hear him still land those high notes with just Russell’s spare accompaniment was to witness that rare pop reinvention that improved upon the original. The duo probably won’t be stripped down when they bring their show to Vegas-on-the-Potomac, but that’s the gamble you have to take.
