"Kenny Chesney: Somewhere in the Sun" (8 p.m., ABC): A wintertime retreat to a tropical island is something most of us can only fantasize about, but it's the real deal for Kenny Chesney. His paradise site -- "somewhere in the Caribbean" is as specific as it gets -- is his escape between concerts and studio sessions. On this special, Chesney performs some of his hits, including "Young," "When the Sun Goes Down" and "There Goes My Life." The program also includes segments from Chesney's July concert tour, both behind the scenes and on stage.
