Twenty-two years ago in Sydney, Australia, then-high-school students Andrew Tierney, Mike Tierney, Phil Burton, and Toby Allen were drawn together by an anachronistic passion for Motown and doo-wop. Nine albums and a 2.5-year residency in Las Vegas later, the fresh-faced foursome are touring the land that spawned the music they love with a tour presented by Smokey Robinson, who joined in on the recording Get Ready on their album and also helped polish production values and fend off mood-killingly weepy clowns. Other classics in the crooning quartet's repertoire include "Ain't No Mountain High Enough," "Dancing in the Street," and an a capella take on "Just My Imagination."
