FOR MORE THAN 40 years, Brian Setzer has been the torchbearer for all things rockabilly since finding success with Stray Cats in the U.K. The Long Island trio relocated to England after hearing about the booming U.K. rock and roll scene there, thinking they might capitalize on it with their own incendiary take on the genre. Sure enough, within months of arriving in England, they had secured a record deal and started a run of hit singles that carried them through two albums before they finally broke big in America with the help of MTV. The video channel was a godsend for any band with the visuals to back up their music. Little wonder that Stray Cats cleaned up, given their unique punk-rockabilly image and the strength of their songs.
