While largely overshadowed by the pop hits he crafted for Monument later in his career, Roy Orbison's work for Sun is deserving of praise. From the aching of ''Ooby Dooby'' or the proto rockabilly of ''Go! Go! Go!'' Roy's work here is solid and energetic enough that all of Texas should be proud. And if you can't shake it to ''Chicken Hearted'' you need to check your pulse.
